Purchased new on Rakuten in March 2025 for 1200 yen. Made of surgical stainless steel, so it can be worn continuously without damage. It's convenient to leave it on while washing hands, taking a bath, etc. Size 10. I hope someone will find it fits! Used for about 3 days. I bought other colors, so I'm selling this one. I hope you like it. ⭐︎Sent by regular mail⭐︎ ⭐︎If you live far from the Kanto region, it may take about a week for delivery⭐︎
