If you'd like anonymous shipping, please let me know and I can accommodate it for an additional 500 yen. My family member used this, but is no longer using it, so I am selling it. It was used about once a month, if that, and has been used less than 5 times. I will also include spare earring backs as a bonus in case of loss. A friend gave this to them, so the material is unknown. It is either silver, stainless steel, tungsten, or titanium. They received permission to sell it, and it was purchased for around 3,000 to 4,000 yen. Unisex. There are scratches on the earring backs, but there are no scratches on the parts that are visible from the outside. I will disinfect it with 80% alcohol before listing it. Please purchase only if you understand that this is a used item.
