These cannabis pipes are hand crafted from a single piece of acrylic polymer material. They are currently available in different color combinations. They have a standard .625 diameter bowl, and a carburetor for easy smoking with superb ergonomic lines that are not only attractive, but also lend to a gratifying experience. The unobtrusive shape and size allow for convenient travel in a pocket or purse. Because these pipes are practically indestructible, there are no worries of them breaking.
