These are cotton rib knit undershirts purchased from Uniqlo. They are a set of two short-sleeved shirts. I removed the tags after taking the photos because they had my name stamped on them. Also, one shirt has a stain of about 3mm in the center. Please check the image. There is some overall pilling from washing, but they are still wearable. Please consider purchasing only if you understand that these are used items. I put them in the dryer, but the fabric is quite durable, and I used them for about two seasons.
