This is a napanapa baby carrier. I bought it for back carrying, but I only used it twice because I didn't have many opportunities to do so. As far as I can see, there are no stains or scratches. There were no leaks during use. napanapa is a Japanese company that sells baby products designed for Japanese people. Therefore, the baby carrier is also designed to fit smaller Japanese people. There is no instruction manual, but you can download it from the official website. If you use the separately sold newborn pad, you can use this baby carrier even for newborns. The regular price is 10,780 yen. Official website: Baby carrier/baby carrier｜napnap official shop https://share.google/hRIljLAZdEDyTDfBI
