Beautiful solid beechwood nuts and bolts in seven different shapes and in the seven colours of the rainbow. Each nut has a corresponding matching bolt for pairing by colour and shape, and each shape has a different number of edges, increasing from 1 to 8. The chunky pieces are the ideal size for young children to manipulate and come in a natural finish to show the grain of the wood. Perfect for learning about colour and shape, for supporting counting and early numeracy, as well as improving manual dexterity and fine motor strength. Includes cotton bag.
