This is a size M medical corset, "Max Belt me2," made by Nippon Sigmax. I purchased it at the hospital when I hurt my back a long time ago. I only used it for half a day on the day I bought it. If you use this type of corset, would you like to have a spare? ^-^ *The box is not included due to shipping costs, but if you need it, I can fold it up and ship it. Please let me know (*ᴗˬᴗ)⁾
