The Grav Labs Octobowl Herb Slide features a built-in glass screen that maximizes airflow while minimizing clogs. It’s a 14mm male slide that’s a perfect addition to any 14mm female waterpipe or rig! This bowl sits atop a rasied stem to really make it stand out! The Octobowls are made from super-strong borosilicate glass which is both heat and break resistant. A thick, extended handle makes this a premier slide for any 14mm female Grav Labs water pipe.
