This is a non-metallic necklace that can be worn with peace of mind by those with metal allergies. The crystal AB stones sparkle beautifully and look great on stage. It fastens with button parts, making it easy to put on and take off quickly, even by yourself. Although it is new and unused, please understand that it has been in the possession of an individual before purchasing. I am not a business, so I do not have multiple items in stock. If you are interested, please purchase it as soon as possible.
