Supernova Smoke you can find a huge variety of metal pipes. Metal conducts heat, so many of our pipes have rubber, plastic, wood or other non conductive grips on the outside of the pipe so you can use them comfortably. The use of interchangeable parts for optimization is of particular utility to the regular smoker. Threaded metal bowls and lids for storage of unused smoking material make metal pipes ideal for travel. Chambered metal pipes are particularly popular as the chamber is a convenient way to store additional smoking material. Metal pipes are (for the most part) inexpensive and indestructible.
