Thank you for viewing! This is a babyGAP knit hat with cat ears, made of fleece-like fabric. It's 51cm. The inside is made of boa material, so it fits snugly and has a very cute design. It will keep you warm even in the dead of winter! Due to the nature of the fleece material, there is some wear and tear, but it was only used by one child, and since there were several other hats, the frequency of use was not that high. There are no noticeable stains, and it seems like it can still be worn for a while! Please note that there may be oversights due to amateur inspection. For those who understand that this is a used item worn by a child, thank you. Please refrain from purchasing if you are sensitive to such things. It will be compressed for shipping. Please understand that there may be creases from folding. It may be shipped via Yu-Packet Post Mini. The shipping method may be changed from Yu-Yu Mercari Bin to Raku-Raku Mercari Bin. Thank you for your understanding.
