RESINWORLD Resin Coaster Molds Set
A crafter favorite for a complete set. This 10-piece kit gives you round and square coaster cavities plus a storage-box holder mold, the platinum silicone releases clean and leaves a glossy mirror finish so you skip top-coating, and the standard coaster depth pours flush. Crafters like that one kit makes a matching set with a holder, and the flexible molds pop the coasters out without cracking.
View on Amazon Editorial illustration.A good coaster mold gives you a glossy, level coaster straight out of the mold with no top-coating, and ideally a matching holder so the set looks finished. Cheap molds warp or leave a dull, uneven surface. Look for platinum silicone that releases clean and mirror-finishes, useful shapes and depth, and a bonus holder mold to round out the set.

What should you look for in silicone mold for resin coasters?
A few things separate a good silicone mold for resin coasters from a frustrating one: platinum silicone, shapes and depth, holder mold included, and level it. Weigh these before you buy.
- Platinum silicone: releases clean and gives a glossy mirror finish with no top-coat.
- Shapes and depth: round and square at standard depth pour flush; deeper molds embed objects.
- Holder mold included: a matching storage or holder mold finishes the set.
- Level it: cure on a level surface so the coasters come out flat.
