If you face the "SL" Logo on the bracelet, the clasp pops open on the left side of the logo. Just pull it open by hand using the side of your thumb. You may need to pull a little hard at first, as we made the clasp sturdy to function well over time. Put the bracelet around your wrist and feed the open clasp through the loop on the other end of the bracelet. You can then close the clasp.
