The typical jewelry worn in a large stretched piercing is a plug, sometimes referred to as a "gauge" or "gauges", which refers to the sizing system used in the U.S. It is solid and usually cylindrical, and may be flared out at one or both ends (saddle-shaped), or kept in place by o-rings fastened around the ends. A variation on this is the flesh tunnel, which is shaped in the same way, but hollow in the middle. Claw-, talon-, and spiral-shaped pieces are also commonplace. Ear-weights in varying degrees of size are also worn, commonly made from silver or bronze, though other metals such as copper or brass are occasionally used. However, some people are easily irritated by some metals; therefore, care should be taken when metal jewelry is worn. Ear cuffs (such as the gold ones utilized in South India provinces) or wrapped bead work (common amongst the Maasai of East Africa) are other options, though are not usually seen in modern Western contexts.
