RESINWORLD 6-Cavity Deep Round Coaster Molds, 4 Inches Coaster Silicone Molds for Epoxy Resin, Coaster Resin Molds for Flower Bouquet Preservation

These round coaster molds are just what I needed for crafting. I used them with remeltable silicone, but they’d be perfect for resin projects too. The shape is classic and functional, and the size works great for actual coasters or decorative pieces.They’re easy to work with, durable, and clean up nicely. A great staple mold to have on hand if you're into epoxy, silicone, or any kind of pourable craft.

These are wonderful resin art project. Fun and easy to use. Works great and also see other types and sizes.

Amazing!! Perfect shape. Easy to clean. Made gorgeous coasters out of them. Not sticky at all!!

The molds are durable and should make wonderful coasters or paperweights.

These molds are perfect for resin coasters! The silicone is durable, flexible, and doesn’t rip even after multiple uses. I love the depth—it allows for layered designs and flower preservation without overflow. The shape is consistently perfect, and the resin pops out effortlessly with a smooth, glass-like finish. No sticky residue, no weird warping—just beautifully shaped coasters every time. Highly recommend for beginners and pros alike!

For the most part it is easy to get molds out. However, one of our molds ripped the plastic so that section in unusable after our first use. We used it to make coasters out of my wedding bouquet. Fair price.

I love the deep mold. It makes for very good coasters.

Better than I expected! Mold is thick and not flimsy at all. Can not wait to use this mold.
