The Wedgits Pink Junior Set integrates a total of 15-blocks that are nested within each other forming a large diamond shape. Wedgits invite complex thinking, experimentation, and construction. They improve spatial orientation, perceptual skills, dexterity, and the understanding of geometric concepts. The Junior Set comes with a clear plastic storage stand and a design booklet with over forty unique product designs. Children are mesmerized with the endless ways that Wedgits nest, link and lock together.
