This fidget spinner is made from a bicycle chain and a skateboard ball bearing. Also, the bearing is removable in case you want to buy another bearing of a different color or for cleaning purposes. Three styles of thumb sticks are available: Cork, Nut and Bolt or Nickel-Plated Iron Screw Post. Very quiet and spins for about 2 minutes. This size does work well with children's small hands and is perfect for an adult. This has to be my favorite spinner I've made! AVAILABILITY: Some of the materials used may be different depending on the availability in the market. Specifically the bike chain itself - some of the bike chains used may look slightly different due to selling out locally. Rest assured that the quality of this product will be of the highest quality possible!
