I can't say for sure because there's no size label, but it was the perfect size for my 6-month-old daughter, so I think it's probably around 44cm. I will ship it as compactly as possible. I may change the shipping method from Rakuraku Mercari Bin to Yu-Yu Mercari Bin. *Please note that the color may look different from the actual item depending on your device. *This is a used item, so please understand that there may be some wrinkles, pilling, fuzzing, and minor overlooked stains.
