This inside out, color changing glass tobacco pipe is fumed with silver and/or gold to give it its color changing properties. It averages about 4" in length, has clear rod work along the stem, and a carb on the end of the bowl. Colors and designs may vary.
An inside out pipe is a pipe that is worked on the inside instead of on the outside like a normal pipe. The disadvantage is that this is much harder to do than a standard pipe so they are a little more expensive but the advantage is that they change colors much more dramatically than normal pipes, making them well worth the cost. If you've ever seen one in person, then you'll definitely agree.
