This simple stacking toy consists of a sturdy wood base with a long dowel, six wooden rings of different sizes and colours, and a wood sphere that sits on top. Stack the rings from large to small, small to large, or any which-way you like. The completed stack with the sphere on top stands 19 cm (about 7.5") tall. Made of sustainably harvested rubberwood with water-based stains that will not chip or fade.
