Spin, swing, and sort! This unique tumbler-sorter will keep your little one engaged for hours. This toy consists of 5 tactile mini-tumblers and a base with a convex bottom. The tumblers measure 19 x 8 cm. The base bowl has a ridge on the bottom that keeps it constantly tilted, and a delightful ringing sound is emitted from the inside. Features of the Spinny Pins (FA248-1): The mini-tumblers are smooth with a coating on one side and have a stunning texture on the other. Each one has a weight inside for balance. The tumblers are stored in the base's compartments. The base bowl has a ridge on the bottom, so it is always unbalanced. This toy can jingle. The materials are BPA-free.
