I found this in a box of children's clothes, so I assume it's for a child, but I'm not sure. It also says "L". It was too big for my 5-year-old, 1-month-old boy (head circumference about 50.5cm). The black part in image 10 is about 55cm around. I will fold it for shipping. #riko's shop list ● Immediate purchase without comment is OK. Even if someone is commenting and wants to buy it, I will prioritize the person who presses the purchase button first. ● I have set the shipping days to 4-7 days, but I will ship it as soon as it's ready.
