Product unavailable but sign up for notifications
Weed Star Bongs are really raising the bar with their 5mm WS Series, with new high quality percolated pipes high on the agenda. This ‘Mad Professor’ is a reworking of one of the most popular perc’d bongs that has ever been mass produced.
The percolator in the centre of this bong is removable for easy cleaning and is now made to an 18.8 joint size.
The shaft features the sandblasted WS Series logo and the mouthpiece is coloured blue. The ‘Mad Professor’ looks really good and hits even better.
