Grav Labs steamroller pipes are made of the same laboratory-grade borosilicate glass as their larger tubes, but with the old-school snap of a handheld dry pipe! This compact steamroller is only 5 inches long, and its two colored glass feet allow you to safely set it down on a flat surface. A color Grav Labs decal is applied in black, blue, red, green, or orange, as available.
