From the Wonderworld I Can Stack & Sort series.
This classic rainbow stacker is popular with young kids in aiding early shape, color and size differentiation skills. With six smooth, easy-grasp wooden pieces to stack on the solid-wood base, it also helps to define hand-eye coordination and grasp manipulation. Best of all, the colours are derived through vegetable dyes which make the stacking rings 100% natural, safe and eco-friendly.
