Chastity device discussions and reviews discussion

Hello, We are considering several devices, but those with an integrated lock often have rather dull key designs. We like the concept of the built-in lock because it makes the device quieter and more compact, yet we want a key that looks good when worn on the neck. Does anyone know how to fix this? I guess it’s a common problem; maybe custom keys are the answer? She likes our current key as is: a simple design with a heart shape at the top where the necklace cord passes through. It resembles jewelry, which is nice, so a purely functional look isn’t ideal for us.
