I purchased this here. It's in good condition and still usable, so I'm putting it up for sale. I used it between the 6th grade of elementary school and the 1st year of junior high school. It has snap buttons to prevent slippage on the arm holder for fractures. The seller said they added two buttons on the upper side because the arm swells for about a week when the fracture is fresh. Please be sure to check the size as it varies depending on height and build. ◎Size: Approximately 19 x 39 cm ◎Belt length: Adjustable up to approximately 68 cm ◎Shoulder pad: Removable, but since it's cylindrical, it's easy to insert when attaching it by pushing the buckle with chopsticks or something similar. ◎Although made with care, there may be some slight discrepancies in the fabric and stitching. ◎It is recommended to wash it in a laundry net.
