Alcare Medical Knee Brace Knee Support Cast - Size L My family member recently injured their knee and purchased this at the hospital. It cost around ¥12,000. A slightly overweight man, about 170cm tall, used this to immobilize his knee for about a week due to a fracture. It was secured over tights, so it did not directly touch the skin. Buying a new one is expensive, so I hope this can be helpful for those who need it. The tape's adhesive strength is not an issue. There is only a little bit of dirt on the surface, which isn't very noticeable, and otherwise, it's in a clean condition. Please understand that this is a used item that has been used once, so please purchase it if you understand this. I cleaned and dried it at home before listing it. I cannot answer specialized questions. There is no dedicated box, so it will be packaged in a paper bag or similar to prevent it from getting wet. Thank you for your understanding.
