I purchased these new with the intention of using them and removed the tags, but after wearing one pair, I realized I had the wrong size. Since I wore one pair, I'm selling a set of 5 pairs. This is a set of 6 pairs, with a retail price of 4840 yen. I'm offering 5 pairs, including shipping, for 2600 yen, which I think is a great deal. I will ship the 5 pairs and one paper tag.
