Thinkamajigs Small Cylinder Blocks

This smaller version of the full-sized cylinder blocks is an excellent exercise in sorting, differentiation, and hand-eye coordination. The set consists of four solid beechwood blocks, each with four cylinders of varying height or diameter. Each block measures 25 centimeters (about 10 inches) long, and the pieces are fully compatible with the full-sized set. Suitable for ages 3 years up.
