I purchased this at a store a few years ago and used it a few times. It's a Spick and Span arm warmer. I believe the retail price was around 10,000 yen. The material is 100% wool. Even with my sensitive skin, it doesn't itch. Size: 10cm wide, 40cm long It's black, so it's very easy to match with other clothes. I've used it a few times and stored it at home, so there is some pilling. Thank you for your understanding regarding used items.
