Thinking Putty is an impressive adult-sized handful of high quality moldable putty. Not just for wiggly children, Thinking Putty is also a stress-relieving, soothing slab of super-smooth elastic putty for tense office workers and impatient computer geeks. It also can be used as a hand exercise for guitar players or therapy for arthritic hands. Each tin arrives with an adult-sized one-fifth of a pound of Thinking Putty and a label that says Crazy Aaron's Thinking Putty. They offered to put our names on the label instead, at nearly twice the price, but we decided that we would let Aaron be the crazy one! We offer many mesmerizing versions of thinking putty. Each tin contains enough putty for a couple of children to use at the same time.
