8" Grav Labs Cup Bubbler
The perfect bubbler for thirst-quenching hits, the 8" Grav Labs Cup Bubbler has thick 50mm borosilicate glass, a 14mm ground glass Octabowl allows for future adaptability with other ground glass attachments.
How it Works
Grind your material and fill the 14mm ground glass bowl with enough for one session. Apply flame to the bowl as you draw; when you've nearly had your fill, pull the bowl out to clear the chamber.
All Grav Labs glass can be cleaned with isopropyl alcohol.
