These opal glass tapers will be shimmering in the light when you wear them. They are meant for ear stretching and of course every day as well. Because they are nonporous, they can be autoclaved to keep them clean. You can choose from a 2 gauge, a 0 gauge, a 00 gauge, a 7/16″ inch, or a 1/2″ inch. These are listed from the smallest to the largest. Due to delicate nature of glass, be extra careful when handling them.
