An individual shiny 9mm December Birthstone drop charm link. This charm can be added to our Italian Charm Bracelets and is also compatible with other 9mm standard size Italian Charm Bracelets. To remove a link: With the front of the bracelet facing you, pull the bracelet apart to expand the links. Whilst holding the links apart slide the link to be removed to the left until it can be lifted out. To add a link: Spread the new link apart and hook it into the open link of the bracelet. Link the ends of the bracelet together using the same method.
