The original Kneadatite (best known as Green Stuff) is used by model makers and hobbyists for conversions, filling mold lines and sculpting miniatures.
Not only did I recieve the kit, but they threw in 2 stickers, a keychain/charm, 2 D20's, a 10 piece silicone set, a 12 piece set, another 10 piece set, and 5 mini D20's.
