The sound boxes set helps improving a child’s auditory sense and memory and the vital ability of concentration. Each pair of cylinders (one red and one blue) makes a different sound when shaken on a scale from loud to soft. The child has to find the matching pairs by listening carefully to the different sounds. A set of rollers can also be sorted by children according to sound from loud to soft.

The set includes 6 pairs of sealed wooden rollers in two boxes.
