Product Review

This Braille Block is made of brightly colored plastic and comprised of a series of eight octagonal disks mounted on a spindle. There are raised dots on seven edges of each disk, while the eighth edge has no dots. Rotate the disks and the dot patterns change so that any pair of adjacent edges will represent any of the 63 dot patterns of the Braille code. Block measures 3 1/2 x 1 3/4.
