EHLE Glass use only high-grade borosilicate glass for their steam-roller pipes and are subject to continuous quality and performance tests.
The EHLE Steamroller pipe consists of a hollow tube open at both ends, and a bowl on one side near one end. You cover the end nearest the bowl with your hand while inhaling the smoke into the tube. Simply release your hand from the end to create the vacuum and inhale the smoke.
Steamrollers are renowned for being harsher on the throat than water bongs, but this is often cited as part of their appeal.
