Used, in great condition. There is a mark on the back, I have shown in the pictures. It looks like it is from an iron, but the fabric is not damaged at all, it is not burnt, rough, or any different to the touch than the other parts of the t-shirt. The mark is only visual. The label on the neck fell off when I was trying to straighten it. You can see it is tech-t model and size M.
 
Size is M
