Since 1998 · Made in the USA
The original silicone-based putty engineered by a former software developer who taught himself chemistry to build something the mass-market version never delivered — texture that feels alive, colors that respond to your hands, and a formula that never dries out.
The Edge
Founder Aaron Muderick spent years teaching himself chemistry and physics to create a silicone-based putty that behaves differently from the 1957 mass-market formula. Every batch is mixed in Norristown, Pennsylvania — not outsourced, not white-labeled.[reference:0]
The non-toxic silicone formula stays soft and stretchy indefinitely and leaves no sticky or slippery residue on fingers — a detail parents, therapists, and adult fidgeters notice immediately.[reference:1]
From heat-sensitive Hypercolor that shifts with body temperature to magnetic putty and glow-in-the-dark effects, each variety is built around a specific tactile or visual experience — not just a color swap.[reference:2]
