Create fun designs with the Skullduggery Perfect Craft Gestures Hand Molding & Casting Kit. First, follow the instructions to make a mold of a simple item of your choice using the Alginate molding material. After that mix the PerfectCast casting material and pour it into the mold that you have created. PerfectCast will quickly harden to perfection in 30 to 45 minutes. After it has set, unmold your creation. Your finished cast will be five times stronger than ordinary plaster casts for durability and longevity. It can be left white or painted with your choice of paint and other embellishments. The set includes 2 pounds of PerfectCast casting material, 1 pound of Alginate Molding Material, an 86-ounce molding bucket and complete instructions. The casting and molding material is non-toxic.
