Materials You'll Need to Make Resin Keychains
Before you start pouring, gather everything in one place. Here's your complete shopping list for making resin keychains at home:
Essential Supplies
- Epoxy resin and hardener — A clear-cure, low-odor formula works best for small castings. Look for brands rated for jewelry and small molds. Expect to pay $15–$30 for a starter kit that will make dozens of keychains.
- Silicone keychain molds — Available in circles, rectangles, hearts, letters, and novelty shapes. A variety pack ($8–$15) gives you plenty of options.
- Keychain hardware — Eye pins or screw-in eye hooks, jump rings, and keychain clasps. A bulk pack of 50 sets runs about $6–$10.
- Mixing cups and stir sticks — Graduated silicone cups are reusable, or use disposable plastic cups. Wooden craft sticks or silicone spatulas work for stirring.
- Nitrile gloves — Always wear gloves when handling uncured resin. A box of 100 costs around $8.
Optional Embellishment Supplies
- Mica powder pigments ($8–$15 for a set of 12+ colors)
- Fine craft glitter or holographic flakes
- Dried pressed flowers
- Small photos printed on transparency film or sealed with clear tape
- Tiny charms, beads, or letter tiles
- Gold or silver leaf flakes
- Alcohol inks for swirl effects

Step-by-Step: How to Make Resin Keychains at Home
Follow these steps carefully for bubble-free, crystal-clear keychains every time.
Step 1: Prepare Your Workspace
Cover your work surface with a silicone mat or plastic sheeting. Resin is sticky and difficult to remove once cured. Work in a well-ventilated room or near an open window — even low-odor formulas benefit from airflow.
Lay out your molds, mixing supplies, and any embedments you plan to use. Having everything within arm's reach prevents rushing once you've mixed your resin, since most formulas give you 30–45 minutes of working time.
Step 2: Mix Your Resin
Most epoxy resin uses a 1:1 ratio of resin to hardener by volume. Measure carefully — inaccurate ratios cause sticky, uncured results.
Pro tip: Stir slowly and deliberately for 3–5 minutes, scraping the sides and bottom of your cup. Fast stirring introduces air bubbles. If you want colored resin, add mica powder or alcohol ink after mixing and stir gently for another minute.
Step 3: Pour the First Layer
Fill your mold about one-third full with mixed resin. This base layer creates a clear window that showcases whatever you embed on top of it.
Use a heat gun or small torch (held 6–8 inches away) to pop surface bubbles. A few quick passes is all you need — don't overheat the resin.
Step 4: Add Your Embedments
After letting the first layer sit for about 20–30 minutes (it should be slightly tacky but not fully set), carefully place your decorative elements. Flowers, glitter, charms, photos — arrange them face-down if the mold produces a glossy top surface.
Placing embedments on a partially cured layer keeps them suspended in the middle of the keychain rather than sinking to the bottom.
Step 5: Pour the Final Layer
Fill the mold to the top with a second pour of freshly mixed resin. Pop any bubbles with your heat source. If your mold has a keychain hole built in, make sure resin fills around the pin completely.
If your mold doesn't have a built-in hole, you'll drill one after curing — we'll cover that in the finishing section.
Step 6: Cure and Demold
Cover your molds with a box or dome to keep dust out. Most epoxy resins need 24–48 hours to fully cure at room temperature (70–80°F is ideal). Resist the urge to demold early — soft resin will dent and warp.
Once fully cured, flex the silicone mold gently and pop out your keychains. They should release easily with a satisfying click.
Finishing and Assembling Your Keychains
Demolded keychains often need a bit of cleanup before they're ready to use.
Sanding and Polishing
If edges feel sharp or there's a slight lip from the pour, sand with fine-grit sandpaper (400, then 800, then 1500 grit) under running water. This prevents dust and creates a smooth finish. For a glass-like shine, follow up with a resin polishing compound and a soft cloth.
Drilling the Hole
If your mold didn't include a hole, use a small drill bit (1.5–2mm) to carefully drill through the top of the keychain. Go slowly to avoid cracking. A hand-held pin vise ($5–$8) gives you more control than a power drill for small pieces.
Attaching Hardware
Thread a screw-in eye pin into the drilled hole (add a tiny drop of super glue for security). Connect a jump ring through the eye pin using small pliers, then attach your keychain clasp to the jump ring. That's it — your resin keychain is complete!
Creative Ideas for Stunning Resin Keychains
Once you've mastered the basic technique, try these popular variations:
- Pressed flower keychains — Embed tiny dried flowers like baby's breath, forget-me-nots, or lavender for a botanical look. These make beautiful personalized gifts.
- Ocean wave keychains — Layer blue and white resin with a tiny bit of sand and crushed shells. Use the techniques from our [Resin Home Décor Projects](/articles/resin-home-decor-projects/) guide scaled down to keychain size.
- Photo keychains — Seal a small printed photo with clear packing tape on both sides before embedding. This prevents the resin from making the paper translucent.
- Galaxy and nebula keychains — Swirl dark purple, blue, and black mica powders with fine holographic glitter for a cosmic effect.
- Name and initial keychains — Use small letter stickers, vinyl cutouts, or letter beads for personalized pieces that are popular sellers on handmade marketplaces.
- Glow-in-the-dark keychains — Mix glow powder into your resin for keychains that charge in sunlight and glow at night. Kids especially love these.
Common Mistakes and How to Avoid Them
Even simple projects have pitfalls. Watch out for these when making resin keychains at home:
Sticky or soft keychains — This almost always means your resin-to-hardener ratio was off. Always measure precisely and mix thoroughly. Check out our [Resin Art Troubleshooting Guide](/articles/resin-art-troubleshooting-guide/) for more fixes.
Bubbles trapped inside — Stir slowly, pour slowly, and use a heat source to pop surface bubbles. Warming your resin bottles in warm water (not hot) before mixing also helps reduce bubbles.
Embedments floating or sinking — Pour in layers and let each one partially cure before adding the next. This gives you control over where objects sit within the keychain.
Cloudy or yellowed resin — Use a UV-resistant formula, especially if your keychains will live on a car keyring in direct sunlight. Store unused resin in a cool, dark place.
Mold damage — Don't use sharp tools to demold. Flex the silicone gently. Applying a thin coat of mold release spray before each pour extends mold life significantly.
Can You Sell Resin Keychains? Tips for Turning Your Hobby Into Income
Absolutely — resin keychains are one of the most popular handmade items on Etsy, craft fairs, and social media shops. Here's what to know:
- Pricing: Most handmade resin keychains sell for $8–$20 depending on complexity and customization. Personalized name keychains command higher prices.
- Material cost per keychain: Roughly $1–$3 including resin, mold wear, hardware, and embedments.
- Photography matters: Clear, well-lit photos on a simple background dramatically impact sales. Natural light works best.
- Batch production: Mix larger amounts of resin and fill multiple molds at once. This is far more efficient than making one at a time.

Frequently Asked Questions
What type of resin is best for making keychains?
Clear epoxy resin with a 1:1 mix ratio is the best choice for keychains. Look for formulas labeled "crystal clear" or "jewelry grade" that cure hard and glossy. UV resin is another option for very small pieces — it cures in minutes under a UV lamp — but epoxy gives you more working time and is more forgiving for beginners. Expect to spend $15–$30 on a quality starter set.
How long does it take for resin keychains to fully cure?
Most epoxy resin keychains need 24–48 hours to fully cure at room temperature (70–80°F). Some fast-cure formulas can demold in 12 hours, but waiting the full cure time ensures maximum hardness and durability. Cold or humid conditions can extend cure times. Avoid handling or attaching hardware until the resin is completely hard to the touch.
Can you put fresh flowers in resin keychains?
Fresh flowers contain moisture that will cause them to rot, turn brown, or create bubbles inside your resin. Always use fully dried and pressed flowers instead. You can press flowers at home between heavy books for 2–3 weeks, use a flower press, or buy pre-dried pressed flowers online ($5–$12 for a variety pack). The drier the flower, the better it preserves in resin.
How do you prevent bubbles in resin keychains?
The three best bubble-prevention techniques are: (1) stir your resin slowly and deliberately instead of whipping it, (2) warm your resin bottles in a warm water bath for 10 minutes before mixing to thin the consistency, and (3) use a heat gun or small kitchen torch to pop surface bubbles after pouring. Working in a warm room (75–80°F) also helps resin flow more smoothly and release trapped air.
Are resin keychains waterproof and durable?
Yes — fully cured epoxy resin is waterproof, scratch-resistant, and very durable. Resin keychains can handle daily use, rain, and normal wear without damage. However, prolonged direct sunlight can yellow some resins over time, so choosing a UV-resistant formula is worth the small extra cost if your keychains will be exposed to sun regularly.
