This is a vibrant set of 8 wooden rainbow nesting boxes, each with a circle on two opposite sides for small hands to grasp. Nest the boxes in order of size, stack them as a tower, or design your own building. The set encourages learning of size differentiation and sequencing. It's also loads of fun for building activities. Made from eco-friendly board using non-toxic paint materials. Features: Handmade from solid, sustainably sourced plantation timber Each piece of the toy is carefully sanded and dyed with food grade colors Please note that these are made of thicker wood with durability in mind and so are heavier; hence, we have rated them as being more appropriate for older children.
