Upline Glass Bong – 12″ – 14 mm
GRAV

Why You’ll Love It
Each restriction in the neck creates its own mini chamber, so smoke and water climb together, cooling and refining flavor before it reaches you. The compact 12″ profile hits like a much larger piece, and the angled mouthpiece acts as a built-in splashguard for clean, comfortable sessions.
Care & Usage Tips
- Fill just enough to cover the downstem (about 1″ of water) to maximize the Upline’s stacking action.
- For easy cleaning, use Formula 420 cleaner or isopropyl alcohol with coarse salt; rinse thoroughly.
- Swap the Octobowl for a 14 mm quartz banger when you want to run concentrates.
Intended for legal use by adults 21+. Keep out of reach of children.
