Blend of Super Sculpey and Super Sculpey Firm. Firm enough to hold its shape, yet soft/malleable enough to comfortably build/shape and blend pieces together. Allows to carve detail into their piece easily. Allows you to use build up methods that are more additive and focused on building out shapes in small increments. Once the clay has been kneaded slightly, it is highly malleable and ready to blend. Cuts down on sanding time because it blends so smoothly
