Small Reusable Silicone Molds

Reusable Silicone Resin Molds — Smooth Gloss Finish for Coasters & Test Pours

These small reusable silicone molds are a go-to for makers who want consistent shapes and a clean, glossy surface straight from the mold. Made with 1/8" thick silicone and a polished interior, they’re ideal for epoxy resin projects where you don’t want to spend extra time sanding and buffing.

Fast Demolding + Ready for Repeat Use

Once your resin has fully cured, simply flex and peel the silicone to pop your piece out. The material is sturdy enough to hold its shape during pouring, but flexible enough to make demolding quick—so you can pour again with minimal downtime.

Great For

• Epoxy coasters

• Small resin art + blanks

• Pigment/colour sample swatches

• Practice pours, mini sets, and more

Mold Release: Optional (Based on Our Use)

In our own pours, we’ve reused these molds multiple times without mold release and haven’t run into sticking or tearing. For maximum mold life (especially with different resin brands), mold release is always a good best practice.
