This amazing little device is an Iolite Vaporizer. One of the most desirable aspects of the Iolite is it's portability. This thing is solidly made, and will pretty much fit in your pocket. It runs on butane gas instead of batteries. The patented flameless catalytic heater has a thermostat so it won't burn your tobacco. It's available in four colors: white (pictured), red, blue, and purple. When ordering please specify your color preference. If not we'll pick for you. This thing is awesome!!
