Brand new, unused. Available in four colors: black, gray, navy, and white. All colors are classic and easy to match with men's clothing. The gray socks have one loose thread. The white socks are over-the-knee. They are slightly smaller in size compared to the others, but should fit around the same time. Size range is approximately 17cm to 22cm. Please use this as a reference for size. This is just my personal opinion, so please consider it as a guideline. I bought these for my third-grade child with 19cm feet.
