Plug (jewellery)
（重定向自Earspool）
A plug (sometimes earplug or earspool), in the context of body modification, is a short, cylindrical piece of jewellery commonly worn in larger-gauge body piercings. Because of their size — which is often substantially thicker than a standard metal earring — plugs can be made out of almost any material. Acrylic glass, metal, wood, bone, stone, horn, glass, silicone or porcelain are all potential plug materials.
