I purchased these new from Uniqlo in January of this year for work and used them for about two months. There is some wear and tear, but I think they can still be used for a long time. This is just my personal assessment, so please understand. Therefore, please refrain from complaints after purchase. If you are okay with the above, please consider purchasing. One of the three pairs is almost unused. There is a spare button in the back pocket. Size: Waist: 76cm Inseam: 66cm (Please note that there may be some errors due to amateur measurements.) Color: Black: 2 pairs Navy: 1 pair Total: 3 pairs
