I can’t have this on my earlobe for more than 5 seconds on the widest lock, and that’s with putting up with lots of pain. The locking mechanism is WAY too tight so I ended up using the plastic ones that came with my piercing kit! These are trash.
Pros
It needed a bit rough on the edge, but I filled it down and it worked great after that.
Cons
The forceps are not suitable for use with particularly small or fine materials
