Take your vaporizing game to the next level with the hand-blown glass Herbalizer Steamroller. Designed with an air carb, this attachment can be filled with vapor and cleared with one large breath. The built-in diffuser holes force the vapor through a small air path which provides smoother hits each time. The steamroller is custom designed to fit comfortably over the Herbalizer magnetic material chamber while utilizing the rubber grips to ensure a snug connection. Due to the inert nature of glass, the vapor production will be more flavorful and all around cleaner. Turn the fan on your Herbie and watch the vapor billow out!
