Thank you for viewing. [Used] Balance Cord Posture Correction Stretcher This is a used item. Please purchase only if you understand that it is a used item. Please refrain from purchasing if you are overly concerned about the condition. I don't know much about the product, but it seems to be a stretcher for improving lower back pain, etc., and it was sold in Korea and other places. It seems to have been sold on Amazon for a while, but it is currently out of stock. Everything in the photos is included. Please judge the condition from the photos. There is no box or instruction manual. Please purchase if you are able to research the product yourself. I cannot provide support. Since there is no box, I plan to wrap the item in air cap (bubble wrap) for shipping. Please be aware of this. There may be periods when shipping is unavailable, so please check the profile description once. Thank you.
