Smooth-On Hobby

Rounding out the craft ecosystem is Smooth-Cast 326, a fast-curing liquid plastic formulated to readily accept SO-Strong and CastMagic pigments for vibrant, translucent, or cold-cast metallic props. For personal keepsakes, Alja-Safe provides a skin-safe, crystalline-silica-free alginate that captures microscopic skin lines for single-use hand and body casting molds, curing quickly and releasing cleanly using warm water.
