Proudly label yourself or others with our Certified Pain In The Ass Crew Socks! Qualifying for certifications can be a nuisance for certain entities - they're often restrictive, require a long time-investment, cost prohibitive, and sometimes they miss the point. But not Pain in the Ass. That's one label that's given out fairly, freely, and often. A fun gift for your super annoying pal or wise ass family member - our Certified Pain In The Ass Men's Socks! Blue Q donates 1% of the sales of their socks to the humanitarian efforts of Doctors Without Borders. Fits men's shoe size 7-12, women's shoe size 8.5-14. Content: 63% combed cotton, 34% nylon, 3% spandex.
