Description: cylinder blocks represent 3-dimensional solids (height and radius squared). With cylinder block n°1, height and radius vary. The variation is constant and 0.5cm in both height and diameter.
The beech cylinder blocks have been designed with slightly rounded edges. They feature a flawless smooth varnish finish, and are individually sanded and lacquered for perfect sliding and to prevent the wood from working over time.
Direct aim: cylinder blocks are a first introduction to visual dimension discrimination.
