This is a Pooh-themed snowsuit purchased from Nishimatsuya. It's a size that can be used from newborn to a few months old. Perfect for those with winter babies! I bought it for my child, and it was only used once or twice. The size is 50-70, and the weight is listed as 3-9 (likely referring to kilograms). It's designed to keep your baby very warm, with the feet covered.
