This fidget spinner is made from a bicycle sprocket (jockey wheel) and chain along with a metal ball bearing. Also, the bearing is removable in case you want to buy another bearing of a different color or for cleaning purposes. Very quiet and spins for about a minute. This size will work well with children's small hands but perfect for an adult. NOTE: LOCAL DELIVERY - If you are in the Charlotte, NC area and purchase any of my products personal delivery is a free service I provide. Please message me before purchasing.
