This bubbler from Zob Glass is one of the new designs they're rolling out. It's approx. 10.5 inches tall and is made of 5mm thick glass. The chamber on this bubbler is 110mm in diameter. This is a big chamber, for big rips! The bent design of the neck ensures a comfortable session that's splash free. The pipe has a fixed flat disc diffuser for cool, clean rips every session. This bubbler comes with an 18mm ground glass slide.
