HEMPER Color Changing PipeDescription This color changing bowl is the first HEMPER piece of its kind! While it may look common on the surface, the real magic happens over time. When clean, the pipe appears transparent with lightly fumed colors but through use, it will turn a dark and rich color! It won't change on its own though, you're going to have to put it to use to reveal the full color change. This thick HEMPER pipe was featured in our xCodeh "Gamers" collaboration box,
