So, I have a pretty annoying allergy... it's to nickel. I know it's not that uncommon... so hopefully someone out there will be able to help me. My Master got me a gorgeous collar from RingOfSteel.net I absolutely love it and the collar doesn't bother me at all. But the collar closes by a pin in the front and then has a lock going through the bottom. (My collar is the basic gorean type but it has gemstones in it.) But the lock begins to irritate my neck and I get a rash and sometimes it bleeds. We are trying to use clear nail polish but we know this will wear off fairly quickly and are looking for a new solution. If anyone can help me find a nickel free lock I would greatly appreciate it!
