Naef Spiel Stacking Shapes The Naef Spiel is a set of 16 angled wooden blocks, each with eight interlocking 'teeth' that allow you to make complex and sophisticated constructions. This edition comes with 4 x 4 different coloured blocks, in yellow, red, green and blue. Precision manufactured from sustainably sourced European hardwood, these blocks are hand sanded to within a tenth of a millimetre. This ensures an incredibly precise slotting fit when building stacks and allows you to fully explore your creativity when building structures. Each of the bright colour finishes used on these blocks are non-toxic, ensuring they are safe for children's hands and mouths. It also acts as a protective layer against human oils and saliva, making these very durable. Naef toys are designed to last for generations, making them a wonderful gift and a beautiful display piece when not in use.
