Set of 4 coasters in one mold. Approx 4 inch per coaster. Please refer to product image gallery for overall sizing.
 
I always recommend using a good mold release whenever pouring resin into silicone molds. Wash with warm soap and water, avoid scrubbing or scratching the mold surface. If you have resin that will not release, use your heat gun to gently release your project from the mold. Sizes are pictured above. Returns or refunds on torn molds will not be accepted.
