Light gray knit cap. Size M (fits up to approximately 60cm). The fabric is quite thick, so I think it's suitable for wearing in the "cold autumn and winter seasons." The size when laid flat is about 20cm, but it's a knit material with good elasticity, so I think it can be used by children to adults. This product is unisex. ・To prevent trouble, please refrain from purchasing if you have strong preferences or concerns.
