These endless hoops have a design that creates a simple round smooth ring. Add beads or pendants to them for fun earring and craft designs. At one end the wire ends with a hole. The other end has a slightly smaller diameter end section. When closing the loop, you insert the smaller side into the hole of the other end. Note: if the ends do not remain closed, simply bend the loop a little to make the ring slightly smaller, then the ends should hold together nicely. These may contain lead and are not recommended for use in children's jewelry.
