This is a knee brace. It has been cut to a length of 42cm so that it can be worn while sitting on a toilet seat (if it's too long, the top of the brace will rest on the seat). You can sit on the toilet with the brace on. This was made for a man weighing 78kg. We will ship within 1-2 days of purchase. Thank you. A knee supporter with a breathable design that firmly supports the knee. #Knee #Brace #Support - Type: Knee supporter - Material: Plastic, metal - Size adjustment: Adjustable straps - Features: Breathable design - Function: Provides support and stability Thank you for viewing.
