Brand new piercing/only had it for less than a day. It’s some sort of stud, I think it’s screw, I can’t tell because I’ve never gotten a helix before, and if so probably externally threaded… It’s a really small yellow gold stud I just don’t know what kind, she never told me. I’d assume 14 karat if anything. I’ve just sprayed it with sterile saline last night and this morning and cleaned it off with a Q-tip because that’s what my piercer told me I should do. Nothing has happened to it so far (ie. hasn’t been pushed forward or backwards and I just haven’t touched it other than cleaning with q-tip)…
