I strive for prompt and courteous service. Two pairs are brand new and unopened, so I've categorized them as new. Please understand. One pair was only worn indoors. The length, laid flat, is approximately 66cm. They come up to above the knee when worn. Thank you for your consideration. Color: Black系 (Black-based) Pattern/Design: Solid Sock Length: Long/Over-the-knee Stains, tears, odors, etc.: None
