Available in various colors, the Metal Pipe Heat Cooler Squadafum has its particularities. Your bowl is closed to prevent smoke and smell from spreading through the environment. It has a spiral part that, after being kept in the freezer, cools and prolongs the path of smoke, making the experience more pleasant and reducing damage. It is worth remembering that our Metal Pipe Heat Cooler Squadafum is a pipe that we recommend using as "One-Hitter” and then redo the cooling process to re-use.
