Chastity device discussions and reviews discussion

My wife is struggling to find an anklet that is stylish, durable, and discreet enough for her Mature Metal stainless steel security screw key. Since she has metal allergies, we’ll likely stick with hypoallergenic stainless steel. We might cut the security key in half and re-drill it to make it smaller, perhaps adding some trinkets as well.

Does anyone have recommendations (links, vendors, styles, ideas, or custom makers) for anklets that match the aesthetic of a stainless steel key, or know of any other successful anklet options?
