Crazy Aaron's Thinking Putty 4" Tin
"Choose your favorite color. You can use Thinking Putty as a toy, a stress ball, a squeeze toy, or as therapy putty. As an office toy, Thinking Putty will draw the jealousy of your co-workers. As a toy, you will never be able to put it down. I promise!" - Crazy Aaron
Thinking Putty is silicone based, not clay or earth based like other modeling compounds. Thinking Putty will never dry out or crumble.
The only reason to keep it in a closed container is to offer protection from dirt, dust, and hair that may otherwise accumulate.
Made in the the USA.
