Konny Baby Carrier Size: XS (Size 7 is the guideline) Color: Black *No size adjustment function. Lightweight and compact. Can be used from 2 weeks old. I previously purchased this on Mercari, but the size didn't fit, so I used it once and have been storing it at home. There are no noticeable stains and it's in a clean condition. Everything in the photos is included. There is no box.
