I have seriously allergy-prone skin. This constantly irks me as all the cute earrings I see are made of cheap metals that break me out something terrible, so I came up with a simple solution so I could wear the cheap cute earrings and not have the skin issues.
On the left, we have a cute pair of Hello Kitty earrings I got at the flea market for 2 bucks. Those hooks would cause my skin to have nightmares. On the right is a pair of sterling silver hooks I got at a craft store. I attached some claw clasps to the hoops on the end of the hooks where the earrings would attach. Now, I buy all the cheap and cute earrings I want, pull the hooks off with a pair of pliers, then clip them onto the silver clasps. One pair of silver clasps that I can use with about 15 different earrings I've picked up here and there for a dollar or so a pair!
