Resin Dice Explained: Sharp-Edge, Liquid-Core, and Inclusion Dice
Quick answer
Resin is the material for artistic, collectible dice. Because resin dice are cast rather than moulded, makers can suspend swirls, glitter, foil, dried flowers, tiny figures, and even a moving liquid core inside them — effects acrylic can't match. The trade-offs: they are hand-poured (more variation), crisp sharp-edge corners can chip, and they cost more and take longer than acrylic. Custom resin dice usually start around 100 sets with ~28-45 day production; in-stock colorways ship fast at a 50-set minimum. This guide covers the effects, durability, and how to order.

What are resin dice?
Resin dice are cast from a liquid resin — usually epoxy or polyurethane — that is poured into a mould and cured into a solid, rather than injection-moulded like standard acrylic dice. That single difference is the whole story: casting is an open, artistic process, so almost anything that fits in the mould can be suspended inside the die. Standard acrylic is cheaper and more uniform, but it can't hold a floating flower, a suspended figure, or a pocket of moving liquid. When you see a die that looks like a tiny sculpture, it is almost always resin.
Sharp-edge vs rounded resin
Resin dice come in two silhouettes. Sharp-edge dice are cast in precise moulds and hand-finished so the faces are flat and the corners crisp, giving a glassy, gem-like look that shows off inclusions beautifully. Rounded dice have softened edges, roll a little more easily, and shrug off drops better. For collector and display sets, sharp-edge wins on looks; for hard everyday play, rounded is more forgiving. We compare the two in depth in sharp-edge vs rounded dice.
The effects only resin can do
This is why brands choose resin. The casting process unlocks a range of effects that make a set feel special:
- Liquid core. A sealed cavity of liquid and glitter (sometimes with a tiny floating figure) so the shimmer visibly moves as the die rolls and settles — the flagship premium effect.
- Inclusions. Real or model objects suspended inside: dried flowers, foil flakes, tiny animals such as cats or rabbits, skulls, stars, or themed charms.
- Swirls and galaxies. Ink swirls, two-tone blends, and glittered "nebula" mixes that give depth and motion inside a clear body.
- Glow and color-shift. Glow-in-the-dark powder or dichroic flakes for night and event-exclusive sets.
You can see a range of these live in our in-stock resin colorways, from liquid-core and nebula sets to flower and animal inclusions.
Durability and play: what to tell buyers
Resin dice are beautiful, but they are a different animal from a tumbled acrylic set, and setting expectations protects your reviews:
- Sharp corners can chip. The crisp facets that make sharp-edge dice stunning are more prone to small chips or scuffs if dropped on a hard table. Sell them as collector or display-grade and pair them with a protective foam box or dice tray.
- Hand-poured means variation. Because each set is cast and finished by hand, tiny differences in swirl, bubble placement, or inclusion position are normal — and part of the appeal. Market artistic sets as one of a kind.
- Balance is play-fair, not casino-grade. Well-made resin rolls fairly, but liquid cores and inclusions add internal features, so it is not the place to promise precision-balanced numbers. If a customer wants to check, our dice balance guide explains the salt-water test.
MOQ, pricing, and lead time
Resin sits in the middle of the dice cost ladder — above acrylic, below metal and gemstone — because it is hand-poured and individually finished rather than stamped out by the thousand.
| In-stock resin | Custom resin | |
|---|---|---|
| MOQ | From 50 sets | ~100 sets per design |
| Sample | Existing set / photo | ~12-21 days |
| Production | Ships in 3-7 days | ~28-45 days by effect |
| Cost tier | Mid | Mid (liquid-core & complex inclusions higher) |
Effect drives cost and time: a simple swirl is quicker and cheaper than a sealed liquid core with a suspended figure. For the full cost drivers and minimums across materials, see the pricing guide and MOQ guide.
How to order custom resin dice
- Pick the effect. Sharp-edge or rounded, and the look — swirl, glitter, liquid core, or a specific inclusion.
- Write the brief. Effect, colors, numbering font and fill color, quantity, packaging, and target ship date.
- Approve a physical sample. Casting effects vary, so sign off on a real set — color, clarity, edge polish, and (for liquid core) the seal — before any bulk payment.
- Confirm terms in writing. Price, MOQ, lead time, acceptable variation, and Incoterms (EXW/FOB) before production.
- Produce with staged QC including bubble and inclusion checks, edge polish, and a leak-risk check on liquid-core designs, plus a final photo before packing.

Frequently asked questions
What are resin dice made of?
Cast epoxy or polyurethane resin, cured in a mould rather than injection-moulded, which lets makers suspend color, glitter, foil, flowers, figures, and liquid cores inside.
What is a liquid-core dice?
A die with a sealed pocket of liquid and glitter at its center so the shimmer moves as it rolls — a premium sharp-edge resin effect that needs careful casting and leak-risk QC.
Are sharp-edge resin dice durable?
Crisp corners look stunning but can chip if dropped on hard surfaces, so they are best sold as collector/display dice with a protective box. Rounded resin or acrylic is tougher for daily play.
Are resin dice balanced and fair?
They roll fairly for tabletop play but have more piece-to-piece variation than mass-moulded acrylic. Good degassing, consistent moulds, and QC keep them coherent; market artistic sets as collector items.
What is the MOQ and lead time for custom resin dice?
Around 100 sets per design, ~12-21 days for a sample, and ~28-45 days production by effect. In-stock resin ships in 3-7 days from a 50-set minimum.
