ZAMST A1 Right M Mid Support Used only twice for medical visits. As shown in the images, it's as good as new. ※ The instruction manual says A1 Short, but the explanation is included with the A1 description. Also, this is the instruction manual that came with the product when purchased, so there is no mistake. ※ We are not in a hurry to sell, so we cannot offer a discount. Thank you for your understanding.
