The HJ-081 is a colorful stacking ring pyramid designed to engage young children as they learn to balance and sort shapes. This set features five rings in blue, red, white, orange, and dark blue, which are topped off with a friendly yellow duck. Weighing only 80 grams, the toy is light enough for small hands to handle easily during play. It comes stored in a practical white mesh bag, making it simple to keep the pieces together when not in use.
