Just like our Bike Chain Key Ring Fidget this Bike Chain Fidget is round like a ring. You can fit it onto the end of your finger and spin it or just stim with it in your hand. These are addictive to fidget with and are small and discrete. The repetitive motion of the bike chain fidgets are very soothing and can help calm or focus. If you are looking for a small and discrete stim toy give this one a try.
