The North Face Socks, Kids, Boys Blue, Yellow, Mustard, Blue, Yellow Size: I don't remember which size I purchased. The third photo shows approximately 15 cm, but my son, who is around 20 cm, also wore them. I'm not sure of the exact size, so I'd like to offer them to someone who is okay with that. The rubber part at the top has stretched from the time of purchase due to being a used item. There are pills and fuzz, and the condition is not good, so I would like to offer them to someone who is not sensitive to these issues. Feel free to ask about combined discounts with other items★
