【Unused】BIEHLER SOCKS MTB Socks for Kids. These are kids' MTB socks, and they have never been used. The size is unknown, but the length from the toe to the heel is 20cm. (Since the socks are made of stretchy material, they might be suitable for children whose feet are slightly larger than 20cm.) Purchase price: Approximately ¥2,500 BIEHLER is a German manufacturer. Founded in 1993, BIEHLER has a long history and aims for a sustainable world for future cycling generations. All products are handmade in Germany. They have partners in Europe, North America, and various Asian countries, strengthening the formation of an international community. Although unused, these have been stored at home, so I would like to sell them to someone who understands that they are pre-owned. Thank you.
