These. Saved. Me. I slept wrong and one of my starter earrings got pushed way too far in. I was in quite a bit of pain for an entire day at work.  I grabbed this luckily because I bought it right after I got my ears pierced. And instantly it removed the back with barely any pain. I got to put it back on safely and not nearly as tight as it was. If you have recently pierced ears/wear butterfly backs on your earrings this is a necessity.
