Totter Tower brings a whole new angle to playtime with incredible tubular style blocks. This wonderful Hape designed open-ended toy is much more diverse than your average set of building blocks. Instead of typical triangles, cubes and rectangles, Totter Tower is made from beautiful natural cylinders of sustainable bamboo that have been sliced into angular sections. After slicing, the edges of each block are given a brightly colored child-safe, flocked surface that keeps them from sliding around when stacked. This unique design allows your little one to build amazing block creations that curve, swoop and defy gravity. Kids can create modern looking landscapes, towers, archways and more with Totter Tower, meaning the fun goes on for hours. The set includes 24 blocks packaged sustainably in a 70% recycled cardboard box printed with water-based inks. Due to small parts, this toy is only recommended for kids ages four-years and older.
