Ariat M3 Loose fit FR jeans size 31/30

Gently used Ariat M3 Loose fit FR jeans in size 31/30. From a non smoking, dog friendly home. Laundered in Gain detergent. Only worn a few times before my husband needed a larger size. There is an oil/grease stain on the right leg about groin-upper thigh level, maybe a minor stain around knee level on right leg as well. There’s a slight discoloration, could be a dye fade or something from the manufacturer, I’m not sure, on the left leg side about shin/knee high. All stitching is intact, button and zipper all function well and like gently used-new. I’ve disclosed all that I see/notice on them but they are sold as is in used condition. Due to oilfield work, it’s possible there are minor oil/grease stains that I may have missed but I’ve looked them over well and didn’t see anything other than what was noted. If you would like more pictures or to ask questions please message me before buying l.
