I see a lot of bad jewelry when I'm doing updates to BME, but this one really blew me away. It's a 6ga tongue bar. As you can see, there appears to be no countersink on the bead (although the bar sort of looks like it might have one), and the threading is wildly exposed with a huge gap. Anyway, if your piercer tries to install jewelry like this in you, or doesn't warn you of the problems if you bring in such jewelry, then you've found a shop that you shouldn't be getting pierced in.
Please don't shop for piercings on the basis of price alone. High quality jewelry is going to cost more, and running a high-end studio is more expensive than running one that cuts corners. By seeking out quality shops and supporting them, you are helping keep this industry top-notch.
