Beautiful solid beechwood giant bolt with seven nuts in different shapes and in the seven colours of the rainbow. Each bolt shape has a different number of edges, increasing from 1 (circle) to 8 (octagon). 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 as well as improving manual dexterity and fine motor strength. The colours match our Rainbow Wooden Loose Parts, Rainbow Architect Sets, Rainbow Wooden Buttons and Rainbow Wooden Nuts & Bolts Sets so can be used in conjunction with these or any loose parts ranges for extended imaginative play.
