This bracelet is made from memory wire. It keeps it's shape so it will stay on your wrist without a clasp and will fit a variety of wrist sizes. Shipping: UNLESS you request otherwise, I ship everything by First Class mail with a tracking number. Upon your request, I can ship by Priority US Mail for $6.00. (Please see my shop policies.) If your shipping address is in Alaska or Hawaii or outside of the U.S., please message me before you purchase so that I can calculate shipping costs. Thanks for shopping!
