This is a baby carrier specifically designed for front-facing (facing the parent) carry. Size is indicated as 1. Authentic, made in Japan. Please refer to photo 6 for sizing. It was used for putting the baby to sleep, short shopping trips, etc., and was very convenient as it is compact. It can also be washed in the washing machine. There are no extremely noticeable stains, but please understand that this is a used item before purchasing. Thank you.
