Wonderfully tactile and versatile construction pieces. Watch as the element of movement is added to the play scene - see the rollers roll across the floor in all directions. Combine with our other building pieces, both small and large, to create colour matched Castles, Palaces and entire Cities. Motor skills are encouraged with the Stacking Game and there is lots to discover with the various colour sorting options. Size: H = 2/4/6/8/10/12/14/16/18/20 cm. 25 pieces in wooden frame.
