Get your little one thinking, tinkering, and learning early! The sturdy rings are each covered with a wonderfully soft, rubbery surface and designed with unique, engraved textures little fingers will love to explore. Meanwhile, built into every ring are magnets, arranged just right so that, no matter which side of each ring is facing up, they'll always connect and stack perfectly from big to small! Or, for more advanced play - How many of the rings can you get to hang from each other all at once? Get a head start on early tactile learning while inspiring hours of exploration with Tinker Rings.
