Purchased new, authentic product in 2023. I bought this thinking it would be necessary when my baby started rolling over, but I ended up not using it and storing it away. There are instruction manuals (English and Japanese versions), but I no longer have the outer box or bag as I threw them away. It was stored folded, so there are quite a few fold creases. Please understand that this is a home-stored item and that there may be imperfections in the sewing due to it being a foreign product before purchasing. SNOOZZZ support belt to prevent babies from rolling over. - Brand: SNOOZZZ - Type: Anti-roll belt - Target age: Baby - Material: Polyester - Included items: Instruction manual Please ask any questions you may have before purchasing. ◆ Immediate purchase is OK. ◆ Shipping is planned via Yu-Packet Post. It will be folded compactly, protected from water damage, and then shipped in an envelope. I am currently raising a child, so I will try to ship as quickly as possible, but it may take up to 2 days to ship. Thank you. Anti-face-down sleeping belt
