It was around 1100 yen at Hands.
I bought it to see what it was like, but I wasn't sure how to use it and gave up.
I tried wearing it for a bit, decided it was too difficult, and took it off immediately. Although I used it for less than a minute, it has been used.
I washed it thoroughly, but
I'm listing it before throwing it away.

Thank you for your understanding of used items.
