Plarail socks, set of 5 pairs. Size: 16-18cm. I bought these for my child who loves trains, but their interest in trains faded, and they outgrew them without ever wearing them. They are new and unused. I have carefully checked them, but as I am not a professional, there may be oversights. I apologize if there are any. Please refrain from purchasing if you are looking for a perfect item. If you have any questions, please feel free to comment. To adjust the thickness for shipping, I may compress them. Thank you for your understanding. If you understand that these are stored at home and if there is a child who will use them, please consider purchasing them.
