I bought this knowing nothing about gauging or plugs, I just wanted a regular earring that looked like a plug.  However, it is thicker than a normal earring post and if you have normal sized holes it will stretch them and it will HURT.  I wore them for a couple weeks after considerable pain getting them in, but decided it wasn't worth the hassle.

Looking back at the product page, the seller makes this very obvious to people who know the terminology, so I really only have myself to blame.  I just advise everyone reading this to make sure they know what the product actually is before purchasing it.

With that being said, it does look really good, but you have to pay attention to the rubber bands so they don't slip off and go missing.
