Hi! i'm a Tardigrade (also known as a water bear). I'm a microscopic creature that can often be found in moss. however i'm capable of living in some pretty extreme environments - even space - thanks to my ability to turn into a "tun." This hard enamel pin is perfect for any science-loving folk. it measures 1.5 inches long by 0.7 inches high and has a double metal clasp on the back.
