Thinking Putty is one of our top putty picks - there are so many ways to play! This otherworldly putty is heat sensitive: the more it's played with, the heat of your hands changes the color from deep space blue to ultraviolet purple to cosmic pink! It has stellar sparkles that shimmer and shine as you stretch it, squeeze it, or twist it. Bring a tin along with you any time your kids need to relax, focus, or daydream. Contains 3.2oz of putty that will never dry out. Made in the USA!
