Choose Your Bracelet from the drop down menu..... Bracelets are adjustable up to 8.5" Lockets are hinged and open like a book with strong magnets to hold the locket closed. Please Note: With the exception of the plain silver heart and both 25mm round, plain or with crystal bracelets, these lockets have a security clasp. This clasp will not allow the locket to be opened accidentally. The locket can only be opened by unclasping the side of the locket from the bracelet chain. We have matching necklaces too. check here... Floating Charms & Lockets
