Kids Cap Hide Trading 100% Polyester Inner Mesh There is a name written on it, which has been erased with a marker. There is no size listed, but it was used by a child around the age of a senior kindergartener. According to the shop's website, it is a size S, 54cm. I have also compared it with a 52cm hat, so please check the photos. To prevent water damage, it may be packaged with recycled materials. Please understand that this is a used item and the packaging method.
