This ain’t no Sculpey… Sugru is a air-cured modeling clay that can be used for everything from molding ergonomic grips to your favorite product to repairing leaky sneakers. Once it’s exposed to air by removing it from its packaging, it can be molded for a 30-minute period and it then cures at room temperature (using the moisture in the air) to a tough flexible silicone in about 24 hours. It’s self-adhesive, waterproof, and dishwasher-safe. Jane will tell you more:
