Grav Labs - Octabowl Glass Slide Bowl With Built-in Glass Screen
Grav Labs glass bong spare and replacement parts are custom made in the USA (Austin, Texas) using only high quality borosilicate glass. The extra-heavy joint helps prevent accidents and the wide opening improves airflow while eight glass stringers form a built-in glass disc screen to help keep ash and debris out of your bong water. A clear glass handle makes this slide bowl easy to lift for an extra rush of air when you inhale, and keeps it from rolling away when set down on a table! Choose from a 14.5mm or 18.8mm joint size when ordering.
