Classic design first made in 1938... and still a favorite today! The rounded wood "rocky" base is a trademark design. There is something appealing about stacking these brightly painted rings! Child is delighted as the cone rocks, spins and topples over spilling the rings. Wood rings make a nice sound when "klacked" together. 4" diameter x 5-1/2" high. Non-toxic finish. Ages 1 - 3 yrs.
