The Braille Cube is made of brightly colored plastic and comprised of three square disks mounted on a common spindle. There are raised dots on three edges of each disk; the fourth edge is left blank. Cube features a 'turn and click' mechanism so the user can feel and hear a complete rotation. Disks can be rotated so the dots form any of the 63 dot patterns of the Braille code. Cube measures 1 x 1. Recommended for children 6 and older.
