Please be sure to read my profile. Thank you. - Size: S (70cm-85cm) I only tried it on for a few seconds over my clothes to check the size at the hospital. I didn't end up using it at all because I could manage without tightening it. I will flatten the box and take the band out of its bag to pack it in a size suitable for the "Nekopos" delivery service. I would appreciate it if this is acceptable to you.
