The six chunky shape blocks in Fat Brain's InnyBin are each designed with fascinating textures that are sure to thrill the fingers. There's a cube, a diamond, a sphere, a triangle, a flower, and the happy Fat Brain logo. As kids push the shapes through the elastic bands of the cube, curiosity is sparked and young minds can't help but explore, experiment, and discover. It's beautifully simple and amazingly mind-expanding!
