My wife is having a tough time finding a stylish, sturdy, yet somewhat discreet anklet to hold her Mature Metal stainless steel security screw key. We'd probably have to go with stainless steel as it's hypoallergenic, as she's allergic to some forms of metal. We'd probably cut the security key in half and re-drill it to reduce its size. Maybe add a few trinkets, etc. Anybody out there have an recommendations (links, vendors, trinkets, styles, ideas, custom makers) that would aesthetically match the stainless steel key, or had any luck with another form of anklet solution?
