This is a handmade Mold made from a Durable plastic that is made for Resin Casting. Pieces pop out easily-May have a few water marks, but a thin coat of resin or resin spray will take care of that. This Mold Features 4 different sizes Kawaii Drink Cup with Heart Centers 3" 2.5" 2" 1.5" Do not put in oven. My molds do not have stands like the commercially made molds do, therefore you will need to balance them from time to time. Pieces made using this mold can NOT be used to remake into molds for resale. Molded From Love 2018
