Grav Labs steamroller pipes are made in the same laboratory-grade borosilicate glass as their larger tubes, though the existing-college snap of a handheld dry pipe!
This steamroller is actually 38mm wide and has a good 14.5mm glass-on-glass joint. Two glass feet permit you to safely arranged that lower on a flat surface, and a carb gap on the left from the tube assists you control your toke. A 14.5mm funnel bowl will be included. A color Grav Labs decal will be applied in black, blue, red, green, or etched, as accessible
