✦ In the event you are not able to put this charm stopper onto your bracelet; since this charm stopper is made up of two parts: rubber ring and silver ring, you may first try to take out the rubber ring from the stopper, next put the rubber ring onto the bracelet, and then put the silver ring after. Once both rubber ring and silver ring are on the bracelet, you can use tweezers to push the rubber ring back into the silver ring
