Thinking Putty is great for children and adults. Terrific for keeping hands busy, plus offers a great option for stress relief and relaxation. Thinking Putty can be shaped, kneaded, stretched, bounced and much more. Soft and pliable, Jam Session adds another dimension - the sweet smell of mixed berries. 0.8 oz. of blue putty, packaged in a convenient storage tin. For ages 3 and up.
