Zara Men's blue dress pants

Slim fit dress pants. Only wore once in like new condition，both back pockets were not opened yet. Extra button still attached. Was properly cleaned after wear. There's a very tiny spot, think the thread came out a bit (see picture). Most likely had it when purchased. Very hard to see. ATTENTION: All sales are final. Please only purchase when you are ok with the condition and sure about the size. Thank you.
