This is a SEV necklace I purchased at a store about three years ago for approximately 30,000 yen. When I was taking it off, I pulled on the clasp, and the parts got caught, causing damage and separating the metal and rubber parts. Currently, only the metal part remains. The metal part is also rusty, and the rubber part has deteriorated. The clasp is broken, so it cannot be worn normally. Therefore, I am selling it as a junk item. The effects of SEV are said to be semi-permanent, so I would appreciate it if you could understand this before purchasing. The original shape is shown in photo 3.
