Size 50-60 Used only twice: for the 15-minute trip from the hospital to home on the day of discharge, and for about 2 hours on the day of the Hatsumiyamairi (Shinto shrine visit for newborns). The hat is unused. It's in very good condition, but please understand that it's a used item due to home storage. The laundry detergent used was Arau, a baby-safe detergent. We recommend washing it once with your own detergent before use.
