The Clementoni Clemmy baby Shape Sorter Tub has 18 blocks of different shapes and colours that can put children into the correct holes of the box's lid. Blocks can also be stacked together to create different shapes. When playing with the Clemmy Baby blocks and the Snap-on box, children improve fine motor skills, concentration, logic, and spatial and sensory perception. The soft, harmless, multi-coloured rubber blocks can also be used while playing in water and can be washed in a dishwasher. The box contains 18 cubes made up of 6 different shapes.
