These are popular sweatpants, a collaboration with Ms. Akiko Tanaka [m4214]. I bought all colors because I couldn't decide, and I'm listing the gray one. I purchased it from the official store and it just arrived yesterday. I can't offer a significant discount due to fees and shipping costs, but I'll sell it at a slightly reduced price. Please refrain from purchasing if you are very particular. Also, I have a black one available. If you purchase both, I can offer them for 6,200 yen, so please comment if you're interested.
