Haggar Cool 18 pants 30X30

Hi, I have four Haggar Cool 18 pants for sale: three black and one blue-gray I sale them by unit for 15$ each or I can sale them 50$ if you take them all. Note: I cut the elastic on one pants because they were to tight (see the last picture). Reason for sale : they are too tight on my waist. I speak French and English at your convinience.
