Thank you very much for viewing this product from among many others. This item was purchased from an online shopping site several years ago, but it has been stored at home for a long time without being used due to the wrong size. I am selling it now to organize my merchandise. Although it is a new, unused item, please note that the outer bag has been discarded. [Product Specifications] Size: M (approx. 50 - 55 cm) Suitable for shoes with 5 or fewer holes on one side (10 total) or for children's shoes. Material: Nylon, Rubber (Spandex) Weight: Approximately 19g, Set Contents: Pair of shoelaces Material: Cool Knot uses 8 strands of spandex rubber. Spandex is a durable rubber also used in medical clothing, and there is no concern about rubber allergies that can occur with natural rubber. [Usage] Can be used with confidence for everyday sneakers, light running, exercise at the gym, and even in hard environments such as full marathons. *Photo ② shows the image of use. I will consider price negotiations positively, so feel free to comment. In that case, it would be smoother if you could present your desired price. For shipping, I will use Yu-Packet Post mini (drop-off at the post).
