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