I received this as a hand-me-down, but I haven't used it, so I'm selling it. It's a mon bebe 7 style baby carrier. The product number is L1500. There is no instruction manual, but you can refer to this for how to use it. (Although the product number is different, the usage is generally the same.) https://lucky-industries.jp/wplucky/wp-content/themes/lucky2019/assets/manual/L2090.pdf It supports not only carrying the baby facing in, facing out, and on your back, but also carrying the baby sideways. It will be folded and shipped in an A4-size envelope. Carry style: Vertical carry, Side carry, Back carry, Forward-facing carry
