Crazy Aaron's Thinking Putty 4"
There are 3.2 ounces of Thinking Putty inside each 4" tin
Thinking Putty contains no latex, gluten, wheat compounds, or phthalates. It is safe for use by people with sensitivity to wheat or latex.
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.
