I purchased this at an outlet. I've used it a few times, but I'm switching to earrings, so I'm selling it. The string in the middle of the case is where the necklace was stored. ◎ The design part is about 6mm long and 8mm wide, and the transparent part of the catch is about 1cm. Please consider this item, understanding that it is a used item m(__)m ◎ If you don't need the case, I will ship it via Yu-Packet Post Mini. If I determine that it's difficult to mail it with the case, I may change it to Rakuraku Mercari Bin Compact. Please be aware of this beforehand. Thank you☆
