18" GRAV LABS STEAMROLLER
This Grav Labs Steamroller is full beast-mode. The Steamroller's super durable 50mm borosilicate glass surrounds a huge chamber with a wide opening on both ends for massive airflow. The 14mm removeable ground glass bowl allows for great versatility with other ground glass attachments.
HOW IT WORKS
Grind your material and fill the 14mm ground glass bowl with enough for one session. Cover one end while you apply flame to the bowl as you draw.
All Grav Labs glass can be cleaned with isopropyl alcohol.
