Thank you for viewing. This is a corrective belt to properly support children's posture from Style. I am selling it because I have no opportunity to use it. It is new and unopened. When listing, I plan to ship via Nekopos (a Japanese delivery service). If the box is too large, I will ship the item itself without the box. Model Name: Style BX Kids Brand: MTG Model Number: YS-AE03SS Size: Height 120-135cm Chest 60-66cm No pets, no smoking.
