12cm BONZA GLASS DIFFUSER STEM WITH CONE

Bonza 12cm glass stem

15mm diameter to fit bonza hole

Includes standard detachable glass cone piece with 14mm joint size.

Features diffuser slits at the base of the stem. The slits of the diffuser break up the smoke so it makes smaller bubbles and is cooled even further by the bong water. The cooling effect makes for a smoother hit that is easier on the inhaler’s throat and lungs.
