This is the LUCKY 1934 ON BACKS Carrier Advance (ラッキー 1934 オンバックス キャリア アドバンス). I bought this intending to use it for carrying my child on my back while doing chores, but my child preferred being held, so I only used it a few times at home before they outgrew it. I think it's still perfectly usable. It has been home-cleaned, but I haven't ironed it, so there may be some creasing in the straps. I do not smoke, and I do not have any pets. The color is navy. It comes with the box and instruction manual. There are no noticeable stains, but please understand that this is a used item and has been stored by a private individual. If you don't need the box, please comment. I will discount the price by 200 yen. Shipping may use recycled materials. Thank you.
