Hello everyone, this is Yassy from Crafters! (・∀・)

I absolutely love making handmade items, looking at other creators' work, and especially collecting wonderful craft supplies! I can easily lose track of time just browsing through online shops.

When it comes to crafting with UV resin, it isn't just the quality of the resin liquid or the UV lamp that determines how your finished piece turns out. The quality of your materials—such as the inclusions you embed inside, the colorants you add, and the silicone molds or open bezels that form the shape—can dramatically elevate the finished quality of your work.

However, when you actually try to shop for resin materials, local physical stores often have a limited selection, leaving many crafters unsure of where to buy. That is why I strongly recommend shopping online, particularly on sites like Amazon.

Online stores offer a vast selection of high-quality, inspiring resin supplies gathered from around the world. In this article, I will share essential selection tips to help beginners buy top-tier, user-friendly supplies online without making mistakes, along with my own trusted recommendations!

Why Buying UV Resin Supplies Online is the Best Choice

When gathering UV resin supplies, some people visit multiple 100-yen shops or local craft stores. However, if you are serious about making high-quality pieces, buying online is the smartest and most efficient choice.

While local craft shops and 100-yen stores do carry charming products, their inventory can be selective or inconsistent, making it difficult to find the exact material you want. Online shops, on the other hand, offer an overwhelming variety of craft materials.

Furthermore, here are three clear reasons why you should source your supplies online:

  • Overwhelming Variety and Value Bundles: You can easily source imported specialty part sets or unique resin colorants that aren't sold in local retail stores.
  • Great Cost Performance: Purchasing multi-packs featuring a wide variety of colors or sizes is often much cheaper than buying individual items.
  • Access to Real Customer Reviews: You can check photos and honest feedback from fellow crafters who have already embedded and cured the materials in resin, helping you avoid purchasing mistakes.

I regularly buy interesting materials on Amazon whenever I spot them. Saving the time I would otherwise spend traveling between physical stores allows me to dedicate more time to actual crafting, making online shopping an indispensable strategy.

Must-Have Resin Inclusions You Can Buy Online

Inclusions are the elements that truly define the charm of a resin piece. Watching materials embedded inside clear liquid resin catch the light and shimmer is one of the greatest joys of resin crafting.

While there are countless types of inclusions online, here is a curated selection of essential items that will immediately upgrade the quality of your work.

1. High-Pigment Holographic & Fine Glitter Assortment Sets

Glitter and holograms are essential when you want to add a brilliant sparkle to your work. Some cheap options can have overly large particles or a dull shimmer.

I recommend purchasing a 12-color or 24-color fine-particle glitter and ultra-thin hologram set online. Ultra-thin holograms do not easily float to the surface in liquid resin, creating a noticeable sense of depth when layered.

Sets containing "chunky iridescent glitter flakes" and "ultra-fine glitter powder" are particularly useful. Choosing polarized types that shift colors depending on the light angle is my secret trick for giving resin pieces a premium look.

2. Fade-Resistant Dried Flowers & Pressed Flower Case Sets

For those making botanical-style accessories, real dried flowers are indispensable. Online stores offer sets containing generous amounts of tiny blooms (such as lace flowers or baby's breath) organized in small compartment cases.

The key criterion when choosing dried flowers is whether they have been properly color-treated. Untreated natural dried flowers can lose their color when soaked in liquid resin or turn brown over time due to aging.

Search online using terms like "vibrant resin pressed flowers" and choose flower sets that have been dyed vividly. These will retain their bright colors even inside resin, giving your piece a professional finish.

3. No-Hole Pearls & Glass Microbeads for a Whimsical Look

If you want to create an effect where objects appear floating gracefully inside resin, "no-hole pearls" are extremely useful. Because they lack stringing holes, no unsightly gaps are visible from any angle, instantly boosting your piece's perfection.

Choose sets with gradient colors or mixed sizes ranging from 3 mm to 8 mm. Combining large and small pearls naturally creates rhythm and 3D depth within your work.

Transparent glass sphere beads (often called bubble beads) are another great option. Simply placing them in resin creates a beautiful appearance reminiscent of real water bubbles frozen in time.

Secrets to Choosing Resin Colorants Online for Maximum Transparency

Choosing the wrong colorant can cause major issues, such as resin failing to cure, turning cloudy, or displaying uneven color. When buying colorants online, always ensure they are specifically formulated for resin.

Beginners are sometimes tempted to substitute acrylic paint or printer ink, but please avoid this. Water-based or high-moisture paints severely inhibit the resin curing process.

Liquid Colorants: The Top Choice for Maintaining Transparency

Liquid resin colorants are the easiest to use for beginners because they blend effortlessly into liquid resin straight from the bottle.

When shopping online, select high-transparency bottle sets that offer rich pigmentation without clouding the resin. Buying a set gives you a complete range from basic shades to muted tones, saving you the hassle of custom mixing.

My personal recommendation is bottles with fine-tip nozzles. They allow you to add color drop by drop, eliminating the risk of making the shade too dark by mistake.

Powder Colorants (Mica Powder & Iridescent Pigments): For Luxurious Pearl Effects

If you want to achieve a mineral-like sheen or a pearlescent luster, buy mica powder. Unlike liquid dyes, mica powder provides a deep, metallic shimmer and opaque luster that rises from within the piece.

Multi-color mica powder sets are widely available online at very affordable prices. If you are creating galaxy-themed or stone-like resin pieces, adding mica powder instantly elevates the visual value of your work. Since a tiny amount provides strong pigmentation, it is exceptionally cost-effective.

How to Select Molds and Open Bezels

Silicone molds, metal open frames (bezels), and pendant trays define the outer shape of your resin craft. Here is what to look for regarding quality when buying them online.

Silicone Molds: Check for Transparency and a Mirror-Finish

When buying silicone molds online, always check whether they feature a "mirror-finish" internal surface. A mirror finish means the inside of the mold is polished completely smooth. Cheap molds without this treatment produce pieces with a cloudy surface that require extra sanding and re-coating.

Additionally, for UV resin, make sure the silicone itself is semi-transparent or clear. Opaque pink or blue silicone molds block UV light from penetrating the back, leaving the interior uncured.

Generous assortment packs containing popular shapes—such as spheres, crystals, gemstone cuts, and geometric forms—are widely sold online and offer the most efficient starting point.

Open Bezels & Pendant Trays: Plating Quality and Smooth Edges Matter

Open metal frames and solid-backed pendant trays are classic supplies for keychains and pendants. When buying bezel sets online, select items with clean, durable gold or silver plating that won't easily peel off.

Excessively cheap bulk sets can sometimes include defective pieces with rough metal burrs (sharp protrusions) or tarnished plating. Be sure to check reviews to confirm that buyers praise the clean plating and smooth edges. Theme-based assortments—featuring moons, stars, animals, or geometric shapes—allow you to experiment with various designs.

Common Online Shopping Mistakes for Beginners and How to Avoid Them

While online shopping is convenient, purchasing without seeing items in person comes with pitfalls. Here are common beginner mistakes and how to prevent them entirely:

Mistake 1: The Item Arrives in a Completely Unexpected Size

Relying solely on product images often leads to surprises, such as parts being too large for a bezel or too tiny to handle easily. Always check the exact dimensions (in millimeters or centimeters) listed on the product page, and keep a ruler nearby to visualize the size before ordering.

Mistake 2: Overseas Shipping Takes Weeks to Arrive

Online marketplaces feature items shipped locally as well as items sent directly via international mail. Waiting weeks for supplies can ruin your creative momentum. Check the shipping origin and choose items fulfilled directly by local warehouses or marked with quick-delivery badges for peace of mind.

Mistake 3: Buying Huge Cheap Assortments and Ending Up with Unused Parts

Massive sets offering dozens of styles for a low price seem tempting, but crafters often only use a few items. Buying aimlessly without a clear theme leaves you with unwanted clutter. Start by buying minimal, high-quality sets suited to the specific design you want to make. A few excellent pieces will help you improve much faster than a pile of low-quality parts.

Yassy's Winning Combination Recipes for Professional-Looking Resin Art

While buying single materials works fine, combining the right supplies dramatically enhances your work. Here are three golden combination recipes I created using materials sourced online:

Recipe 1: Deep & Mystical Night Sky / Galaxy Theme

  • Colorants: Liquid colorants in deep blue, purple, and magenta.
  • Base Material: White mica powder.
  • Inclusions: Iridescent chunky holograms, micro-sized gold star metal charms.
  • Mold/Frame: Moon/star open bezels or a crescent moon silicone mold.

Pour a thin base layer of resin mixed with a tiny bit of white mica powder, then layer a blue-to-purple gradient over it. Finish by placing chunky holograms and star charms inside. This technique creates a radiant night sky effect with captivating depth.

Recipe 2: Elegant & Delicate Botanical Herbarium Style

  • Colorants: Clear resin (uncolored) or extremely subtle pale pink liquid colorant.
  • Inclusions: Dyed dried flowers (lace flowers), no-hole pearls (white/pink mix), gold leaf flakes.
  • Mold: Perfume bottle or teardrop silicone mold.

Using high-transparency resin, carefully arrange dried flowers using tweezers. Scatter small no-hole pearls and torn bits of gold leaf between the petals. The gold leaf instantly adds sophistication, giving the finished accessory a professional look.

Recipe 3: Luxurious Raw Gemstone / Amethyst Look

  • Colorants: Liquid colorants in purple and clear black, gold mica powder.
  • Inclusions: Crushed glass particles (purple and clear), fine glitter powder.
  • Mold: Raw mineral/crystal silicone mold.

Fill the bottom of the mold with crushed glass, then pour in purple resin mixed in varying tones. Finally, swirl in a small amount of resin mixed with gold mica powder to create a marble effect before curing. Held up to the light, this piece sparkles with complex, stone-like grandeur.

Proper Storage Methods to Keep Your Materials Fresh

Once you acquire great supplies, store them properly to prevent degradation over time. Proper care keeps your workspace efficient and maintains material quality.

Protect Dried Flowers from Moisture and Direct Sunlight

Dried flowers are delicate. Leaving them in original flimsy packaging exposes them to humidity and sunlight, causing mold or fading. Place them in an airtight container with silica gel desiccant packets and store them in a dark drawer.

Keep Silicone Molds Dust-Free and Undeformed

Silicone naturally attracts dust due to static electricity. Pouring resin into a dusty mold embeds lint permanently into your piece. Gently remove dust using masking tape after use, and store molds in zippered plastic bags. Store them flat or standing upright without stacking heavy objects on top to prevent deformation.

Conclusion: Enjoy Creating Resin Art with Great Online Supplies!

In this guide, we explored the best UV resin supplies available online, along with key selection criteria and combination techniques.

To elevate your UV resin craft, it is essential to consider not just the resin liquid, but also the choice of inclusions, colorants, and molds. Online shopping opens up infinite possibilities to fuel your creativity. By following these guidelines, you can avoid common buyer mistakes and bring your imaginative designs to life with confidence.

The excitement of opening new supplies and crafting your own unique pieces is truly wonderful. Make the most of online sourcing to create your very own special resin artwork!
