Flesh Tunnel
From BME Encyclopedia
Flesh tunnels are large (or sometimes not so large) tubes that are placed through large stretched piercings. Most commonly, they are placed through earlobe piercings, but may also be worn in nipple piercings, frenums, hood piercings, tongue piercings, or practically any larger piercing.
A plug is generally a solid tunnel (i.e. no hole through the middle).
