This is a set of a Konny baby carrier and a hip seat. I'm selling them because I no longer use them. The Konny carrier was purchased in 2020. I think I used it for about six months in total. I bought an Ergobaby carrier in the meantime, so I kept the Konny carrier in my bag just in case. I sometimes used it to put my child to sleep, so there is some wear and tear, but I don't think there was much change in size, perhaps because the fabric didn't stretch much. The included storage bag is not included. The hip seat was purchased at Nishimatsuya. I think I bought it in 2022. I used it a few times. I also kept this in the car just in case. The part where the child sits opens up, so you can put a small amount of luggage in it. Please understand that these are used items and have been used by a child.
