Tunnels and plugs which are made of different types of glass and stone.
All tunnels & plugs are sold as single. Not as a pair!
TIP 1: Glass tunnels and plugs can be safely cleaned with alcohol or (anti-bacterial) soap.
TIP 2: Never wear your glass tunnel or plug while swimming or taking a shower. It may slip out of your piercing causing it to fall and possibly break. Oops!
