The fumed glass twists perfectly and elegantly in the center of the hand pipe. You can actually see the space caused by the design, leaving a small window in between the tubing. Your smoke follows the curves of both tubes, creating a truly unique smoking experience. The fumed glass is featured throughout the entire Overlap Twist Spoon Pipe. Fumed glass changes colors based on the amount of light it is exposed to. This kind of glass will give you a different looking pipe the more you smoke it as well, as the residue will darken the insides. A used pipe will look more interesting than ever. The color choices pertain to the striping located on the bowl and towards the mouthpiece. These colored stripes fully circle the pipe, even on the inside of the bowl. Available in red or blue, these stripe accents make the pipe stand out more while not affecting the overall fumed coloring of the glass. The Overlap Twist Spoon Pipe is about 4.5 inches long and has a base width of 2 inches. The bottom of the head of the pipe is flattened slightly to prevent any chance of your pipe rolling over, therefore spilling your packed bowl and ash all over. Any chance of avoiding this kind of headache is worth it. This hand pipe has a carb hole on the side to regulate airflow. Regulating airflow gives you a chance to control the degree at which you burn your herbs. Holding and releasing the carb hole can give you larger hits and more potent smoke.
