Steamrollers are pipes that feature a streamlined cylindrical design. The positioning of the carb is at the end of the pipe, instead of the side of the bowl. When released, this allows air to travel more easily through the pipe, giving you a smooth smoking sensation.
Steamroller pipes come in two distinct designs: One for herb users and another for concentrate users. These two designs are distinct enough where they are not interchangeable, so users will have to decide which they want to purchase.
