Frit Hand Pipes are created by melting small pieces of colored glass, called “frit,” to line the inside of a glass pipe. Frit adds a second layer of glass to the inside of the pipe, so these pieces are usually thicker and more durable than the average pipe. 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.
