This is the mini version of my bike chain fidget spinner and is made from a bicycle chain along with 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 perfect with children's small hands and an adult. This style is my personal spinner and I just hook it to a harbinger and put it on my key chain! 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!
