Please review the 4th photo for instructions and watch this video showing how to use the kit: https://bit.ly/2Hew3bw (The video shows our old kit from 2014, but the only differences with the new version are the height of the urethane pucks included in the kit, and that we no longer sell the bracelet mandrel. We will be filming a new video soon.)All Sales are FINAL. No Returns, Refunds, or Exchanges.
