Thank you for viewing. Adjustable crutch to support the knee, black and blue design. I used this after breaking my leg skateboarding in November of this year, including for one month post-surgery and outdoors during the non-weight-bearing period. I cleaned the bottom parts with alcohol every time I used it outdoors, but there are some dirt and scratches from use. The grip hasn't weakened, so I don't think there are any particular problems with using it. All parts are included. Assembly is easy. Thanks to this, I was able to return to work a month earlier, and I could easily do things like shopping, which can be a hassle with crutches. I'm confident that it improves your quality of life compared to crutches. I have wiped it down with water and alcohol. *Please note that this is a used item, and the outer cardboard box was slightly torn during the initial opening. Therefore, I have set the price a little lower, including shipping. It's difficult to lower the price at the moment because of the high shipping costs. If you have any questions, please ask in the comments. - Brand: iWALK 3.0 - Type: Knee Crutch - Color: Black/Blue - Accessories: Instruction manual, all parts - Adjustable: Height adjustment function available
