My first pair are marked

Poor customer service

"The boxer briefs were comfortable and fit well, however after a single wear and one wash(done with the proper care) several pairs already have holes in them. I’m extremely disappointed at trying to contact the company several times they still will not respond. My advice is to stay away."
