These are KALNA sweatpants. The retail price was a little over 20,000 yen. I've worn them 3-4 times since I bought them, and there are no stains or tears. They're stylish sweatpants for adults and look cool. The logo on the back pocket and the frayed thread damage are part of the original design. Please refrain from purchasing if you are sensitive to used items, as perceptions may vary.
