This little fidget is difficult to put down. It is simply 24 triangles that are linked together so that it bends and folds in your hands. Each section is meant to be able to pivot and fold in different ways so you can manipulate them in many different positions. Basically it is a never ending folding and twisting snake toy. You can open and fold it over and over again. Straight line is 12" long x .5". Comes in 3 colors: Red/White, Green/White, and Blue/White.
