4x2 (2x1.5 per piece) inch bookmark silicone mold.  Good for hundreds of uses when cared for properly.
 
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. Remove any residue with 91% alcohol. 
Returns or refund on torn molds will not be accepted
