This set contains 3 rods and 10 colorful circular disks in a wooden box.

The objective of this toy is to move the disks to another rod – one at a time. A bigger disk cannot be placed on top of a smaller disk at any point.

This mathematical toy helps improve the logical skills and brain development of a child.

The three rods are screwed into the lid of the box. The box then acts as the stand for the disks to be placed on.
