Pros: Price, Quality, Size, Ease of Use
Cons: wish there was something a bit more permanent.
"This product is great. I put it on a base metal chain I created for myself because I am allergic. I have to put it on the necklace about once every week and a half but I use the necklace almost every day. The only thing I wish is that there was something out there more permanent for those with allergies to base metals."
