These are familiar white socks. They have a slightly off-white impression rather than being pure white, but I consider them to be almost white socks. The familiar "F" mark is embroidered on the outside of the ankle. I discarded the tag, so I'm not certain of the size, but I wore these when I was wearing 15-16 cm shoes. Please understand that the size selection is for convenience when listing the item. I purchased these new at a store and carried them as a change of clothes, wearing them a few times. I didn't use them as my main pair, so there are almost no noticeable frays or stains, but please be aware that there is some wear and tear, such as slight blackening and pilling. Please consider them if they are within your range of use. #familiar #ElementarySchoolEntranceExam #Ojuken (Entrance Exam) #KindergartenClass #Formal
