Thank you for viewing. I purchased this from Akachan Honpo shortly after the new year (retail price 28,490 yen), but when I tried it on at home, it didn't fit well for me, as I have a bad back, so I'm reluctantly putting it up for sale. I haven't used it for even an hour after opening it, so it's practically unused. There are no stains or anything. I've only had it for about a month since I bought it, and I've been storing it at home in its box. Please refrain from purchasing if you are sensitive or concerned about this. I will ship it in the box, but I threw away the bag that the baby carrier came in, so it will be shipped without the bag, or I will use a substitute. This is a hip seat carrier made of breathable mesh material, suitable for the growth of your baby.
