I purchased this online and only tried it on once over my clothes, but I've decided it's not for me, so I'm offering it to someone who wants it. The outer box will be folded and shipped with the item via Nekopos. Japan Sigmax MedyAid Style Care Back Stretch S-M. Suitable size (approx.): Waist 60-80cm. Improves posture and body alignment, corrects slouching, promotes beautiful posture, and provides stretching and support. It cost over 3000 yen including shipping when new, so I think this is a good deal, even though it's a used item.
