I have kept this item in storage since I purchased it, and it is unused. This is a back posture correction belt with an integrated waist belt. It has a double-cross structure that securely fastens and fits the body. This item has been stored for a long time. The box has some discoloration. Please refrain from purchasing if you are concerned about this. The size is L, and the waist size it fits is 75cm to 95cm. The box will be folded and the item will be shipped without the box. This is a Minoura Yamada-style Katalaq One-Touch Belt. * This posture correction support belt was devised by a doctor. * It helps to correct back posture, such as for a hunched back, and maintain proper posture. * It is made of thin mesh material, so it is not noticeable under clothing. * The strength can be freely adjusted with the cross belt and waist belt. Thank you for looking.
