Thank you for looking. This is a listing for a NEENCA knee support (fiber material/hand washable). I purchased an XL size, but it didn't fit, so it has only been tried on once and is almost unused. The box and instruction manual are included. There are slight scuffs on the outer box, but the main unit is in clean, like-new condition. Made of soft and stretchy fiber material, it provides firm knee support while being comfortable to wear. It is hand washable, so you can keep it clean. ■ Product Details ・Brand: NEENCA ・Size: XL (※This listing is for the XL size) ・Material: Fiber material ・Care: Hand wash recommended ■ Price This product is sold on Amazon for around ¥6,698. It is listed for ¥3900 with almost no use and including shipping, so I believe it is an affordable price. ■ Shipping Yū-Yū Mercari便 (anonymous shipping) Usually ships within 4-7 days.
