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.

The silicon is thin but very durable. The cup sizes are great for what I needed measuring from inner edge of about 8.5 inches all four ways. The cups are deep. The piece is super versatile as the mold can for candle making, baking, resin design making, etc. super versatile. Great quality product.

These round coaster molds are perfect for embedding objects in the coasters. Each mold uses approximately 4 ounces of resin so it is quite a bit but I actually love the thickness. I have made a few projects with these and they demold easily. The molds are sturdy and a good quality. I highly recommend them!

Product is just as advertised. It is super easy to demold. Works great!

These coaster molds are just the right size! Great quality silicone and easy to use — perfect for resin projects or DIY gifts.

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.

Great product, epoxy easy to extract, except where I was too aggressive with the torch to remove air bubbles 🫩. So don’t you do something that stupid.

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!

Parfait. Le démoulage se fait super bien.

Stunning! I put some my mothers’s and father’s ashes in them for my family.

It stuck to the mold and literally took a piece out of it when I was taking out my cured coaster.

First 5 coasters I made turned out great. No issue with the mold. The 6th one stuck to the epoxy resin and tore while I was removing. This was my first time using this product. Things started very good but end very poorly. Wouldn't recommend.

Cannot remove the coaster and the mold ripped.
