The Fume WigWag Hand Pipe is created through a process of vaporizing a precious metal, such as silver or gold, into clear glass. These fumes are melted into the glass, giving the glass an iridescent aesthetic. As these pieces are used, the metal fumes in the glass refract light much like a prism, which causes the pipe to appear to change colors. The WigWag feature on the front of the bowl is a classic design with a mixture of colors that swirl into a spiral pattern. These pipes are small enough to fit in your hand and have a carburetor, which is a hole on the side of the pipe near the bowl. The “carb” allows fresh air to mix with the smoke in the chamber, resulting in smoother hits, better taste and less coughing.
