If you love your Herbalizer and want to take that enjoyment a stage further then the Steamroller is exactly what you need. It is a 9 inch tall cooling tower made of clear hand-blown glass with a carb hole in the side and a Herbalizer logo on the front . The bottom fitting is designed to drop perfectly onto your herbalizer and the Cool Grip seals ensure a perfect fit. The smooth mouthpiece has been designed with perfect comfort in mind to make sure using your Herbalizer Steamroller is as nice as possible. The inner chamber acts to help diffuse and filter the smoke which improves the flavor even more over the standard Herbalizer so you'll be loving it even more than you ever have.
