This is a waist belt that supports the pelvis and lower back, reducing the strain on your lower back! *Size is M!* I used it once, but it didn't fit me, so I'm selling it! I bought it for 3980 yen! I've only used it once, so it's in very clean condition! Due to shipping costs, I will fold the box for shipping, so I would appreciate your understanding. Price is not negotiable. #Corset #WaistBelt #LowerBackPainRelief #Pelvis - Brand: LUTECH - Model Name: Gear Bold 12 - Features: Waist belt, lower back pain relief, adjustable - Color: Black - Size: Free Size Thank you for looking.
