Goodnight Cactus Thinking Putty

A color-changing putty that responds to warmth from your hands. Knead and stretch it from the reusable tin and watch the surface shift as the material warms.

The Hypercolor putty comes in a 3.5-inch tin and responds to warmth from the hands. Check the age and surface-care guidance; it is not food or a treatment for a health condition.
