Thinking Putty Super Oil Slick inspires with its metallic shimmering flip-flop color shift, reminiscent of the light reflections on an oil slick. In addition to its visual features, this special putty impresses with fascinating physical properties: it stretches like chewing gum, tears like paper, bounces like a bouncy ball when shaped, and shatters under sudden impact. This putty is suitable both as an anti-stress tool in the workplace and for targeted hand and finger training in occupational therapy. The putty is delivered in a sturdy metal tin for clean storage. Furthermore, the material is proven to be free of BPA and gluten.
