Weed Star 4-Arm Diffuser Precooler
This is a very special Weed Star Pre-cooler because it features a 4-arm diffuser to provide an extra smooth smoke. The main joint is 29.2 (Zumo size on a Roor) and the detachable 4-arm diffuser slots into it, reducing the joint size to fit an 18.8 bowl.
The 4-arm diffuser could also be utilized on a Roor Zumo 29.2, as it is just about long enough - unless you like your diffuser ends to be right against the glass at the bottom.
