The shirt itself is in excellent condition.
However there are 2 marks next to each other on the back of the left sleeve, possibly sharpie not too sure.
it's hard to capture them since it's black on black but I tried to highlight the more visible one in the pictures I put up.
Let me know if you need any more pictures.
