Grav 19mm Cup Bowl

The GRAV 19mm Cup Bowl is a clear replacement bowl that fits any 19mm female joint. GRAV makes scientific-style smoking glass from borosilicate, the same heat-resistant glass used in lab equipment, so it is strong and easy to clean. A glass maria (a ring) around the stem gives you a cool spot to grip when you pull the bowl, so you do not burn your fingers. The cup shape has a limited capacity, which GRAV designed for smaller water pipes and its Helix pipes, and it helps you avoid overpacking. Pick one up to replace a broken bowl or keep a spare in rotation so you always have a clean bowl. Fits 19mm joints only; check your pipe’s joint size first. Sold as one bowl.
