You are buying 12pcs for the price. This is a raw unfinished brass cuff bracelet. At one time,many years ago, we used to solder things to this base when we made jewelry. These are pretty thin and bendable. American made. Look to be about 5.5 inches in length. 4mm wide and about 7mm at the split where you would mount something. They are going to fit most woman fine. I have had them hanging around the shop here for years maybe some other jeweler can use them. New old stock.
