I found this today and bought one for my wife (KH). Thought I’d share with the CM community. https://bearfruitjewelry.com/collections/bracelets/products/key-double-chain-bracelet Grayfelix
My wife wears a necklace with my key on it, it is such a tease every time I see it on her... She is the best and doesn't even need to try.
Its my wifes birthday coming up in a few weeks, I was at a loss as to what to get her, but I will look into a nice necklace that I can put the key on. It still sits in a draw next to our bed so would be a good "handing over" of the key as such. Thanks for the link and the idea
