Our own recipe for Special Effects Gelatin. Simply take a cube, place it in a microwave safe container, slowly heat it up (7 seconds at a time until you determine how your microwave effects the gelatin). Then, either use it to fill your own molds, or do a safety test (heat check) and apply directly to your skin to create build-up makeups. Paint to your hearts content, then peel off and melt down again. Cubes are not infinitely reusable, but you can typically 10-12 uses out of each. Choose the color that most closely matches you skin tone. Every bag comes with 7 Gelatin cubes.
