Crazy Aaron's Thinking Putty MINI- Stocking Stuffer

Play with your Thinking Putty at home, school, work, the car, so you can have fun and relieve stress while your brain ponders infinite creative possibilities. Thinking Putty is silicone-based, so it will never dry out or crumble. Keep it in the tin when not using to protect the putty from dirt, dust, and hair that may otherwise accumulate. Each tin contains it's own effect including shifting colors due to light, glow in the dark or a hypercolor which changes color due to heat.
