These glow-in-the-dark science socks for men are covered in test tubes, pipettes and Erlenmeyer flasks bubbling with green and blue liquid. What exactly is that stuff? We like to call it “chemistry juice.” Real chemistry might be a little less colorful, but it doesn't look nearly as good on a sock! Fits men's shoe sizes 8 to 13. 62% cotton, 35% polyester, 3% spandex. Made in Korea.
