Just be sure to keep them scrupulously clean, particularly the one up in the cartilage. You do NOT want to let that one get infected, trust me. I used to work at an Earring Tree, so did plenty, and saw the results of ones that weren't taken care of.

No, I have no piercings myself. No desire to, not afraid of it, just don't want any. Enough allergies in my family, including metal allergies, that it's just not worth the risk.
