How to Make Resin Keychains to Sell
Resin keychains are one of the best products for starting a small craft business, and not because they're easy (they are) — because the economics work. Material cost per keychain is under $1 when you're buying resin in reasonable quantities. They sell for $12–25 at craft markets and $15–30 on Etsy. The margin is real.
They're also fast. You can pour a dozen in one session, demold the next day, and have finished product in 48 hours.
Here's how to make them well, and what actually sells.
What makes a keychain sellable
The keychains that sell consistently have three things: a shape people connect with, a clean finish, and hardware that looks like it belongs there.
Shape. Geometric shapes (circles, teardrops, hexagons) are perennial sellers. So are local references — a province or state outline, a regional landmark silhouette. Novelty shapes (animals, food shapes, pop culture references) can sell fast at markets but may not have staying power in an online shop.
Finish. Scratched or cloudy pieces sit in a bin. A clean glossy finish with no bubbles or surface defects is the baseline. This means good molds, proper mixing, and basic finishing — not hours of sanding, just not skipping the basics.
Hardware. A keychain ring attached with a cheap lobster clasp that opens by itself is worse than no clasp. A heavy-duty swivel snap hook or a solid-weld keyring gives the piece weight and reliability that customers feel. The hardware is 5–15 cents more per piece. Worth every cent.
Molds for keychains
Keychain molds are thinner than pendant molds in general — a good keychain is maybe 4–6 mm thick, light enough not to drag a key fob down. Many keychain molds have a built-in loop at the top (a cavity that creates a resin loop for the ring to thread through), which is elegant because there's no drilling or gluing.
If the mold doesn't have a built-in loop, drill a hole after curing or use a glue-on bail. For keychains specifically, drilled holes are more durable because the loop takes repeated mechanical stress every time the keychain is used.
Silicone molds for keychains are available in sets or individually. A set of 6–8 different shapes gives variety for a market table without overwhelming your production.
The pour
Standard casting epoxy, same ratio and mixing process as any other resin pour. Keychains have a large flat surface, so bubbles that don't pop during the torch pass will show clearly. Pour, wait 5 minutes, do a careful torch pass, then cover.
If you're adding inclusions — glitter, foils, dried botanicals, letters — the approach depends on the item:
Glitter: Add to the mixed resin before pouring. Chunky glitter sinks; fine glitter stays suspended better. Shake the mold gently after pouring to help glitter distribute.
Foil flakes: Pour resin, wait for it to get slightly tacky (1–3 hours), then place foil flakes on the surface. They'll sink in slightly and stay put. Top with a thin clear pour if you want them fully encapsulated.
Text or photos: Use resin-coated paper inclusions (seal with Mod Podge or UV resin before embedding) to prevent the paper from absorbing resin and going transparent.
Dried botanicals: Two-layer pour as described in the flower embedding guide.
Hardware and assembly
Keyring / split ring: The classic key ring (15–25 mm diameter, heavy gauge wire). Open with a key ring spreader tool — trying to open them by hand damages your fingernails and bends the ring. Available in silver and gold finishes.
Swivel snap hook: A bolt snap hook that swivels — better for bags and backpacks where the keychain hangs and rotates. More expensive than a simple ring but looks more professional.
Ball chain: A length of ball chain (like the kind on military dog tags) with a connector. Easy to cut to custom lengths. Casual look, popular for gift shop style keychains.
For connecting the hardware to the drilled hole: a jump ring (6–8 mm, 18 gauge) handles the transition. The jump ring goes through the drilled hole; the keyring or snap hook clips to the jump ring.
Pricing and quantities
For craft markets: $12–18 for standard keychains, $20–28 for ones with more complex inclusions (real flowers, foil work, personalization). Don't go below $10 — buyers who look for the cheapest keychain aren't your customer.
For Etsy: you can go a bit higher, especially for personalized or custom pieces. Add a "custom name" listing and charge $20–30 for a personalized keychain — this is one of Etsy's consistently strong categories.
Batch production is where keychains make sense financially. If you're making one at a time, the economics are less compelling. Set up a batch of 12–20 identical or related pieces, pour them together, finish them together. You'll have product for a month from one afternoon's work.
What I'd make if I were starting from scratch
I'd start with three shapes (a round disc, a teardrop, and a simple geometric), two colorways (one warm, one cool), and one glitter variant — maybe a gold-flake pour on clear. That's a modest but cohesive range that photographs well together and gives a customer something to choose between.
Add dried flowers when you've got the basics down. The flower pieces are the ones that consistently stop people at a market table.
