I have been storing this at home for a long time. I cleaned it this time by soaking it in baking soda. Heart part: Approximately 15 x 10mm The box is not included! Total length: Approximately 39cm, including the clasp The box is not included. I haven't used it, but I stored it without putting it in a bag or anything. I think it's a souvenir from Hawaii. I only checked for scratches with the naked eye. I would appreciate it if you could understand the above.
