This barbell would be acceptable for use at The Hole
Gallery. Notice the threads and are not visible, this
is called an Internally Threaded Barbell. The
threading for this jewelry is connected to the ball
and inside the post. This ensures smooth insertion
with no tissue damage. This also makes buying just
new ends or just a shorter post possible rather than
purchasing new barbells everytime.
This is an example of an Externally Threaded
Barbell. This type of jewelry is very popular
amongst piercing studios because of its low cost.
External threads can tear and damage tissue upon
insertion or removal and is generally made of very
low quality materials. The balls on this jewelry are ill
fitted and leave a gap between ball and post. Such
gaps run risk of harboring bacteria and increase
chances of infection.
