WS - Removable Dome Perc with Piercings - 18.8mm Male Joint

This dome perc tree is a spare or replacement part for the WS Mad Professor 2.0 (but not the Mad Professor 3.0, which has a male joint inside the tube), but it can can be used in any removeable perc bong with an 18.8mm female joint, like Weed Star's Mahony! This piece features an 18.8mm glass-on-glass male joint, a dome perc with 12 piercings around the tube, and a blue glass loop at the top for easy maneuvering down your bongs cylinder with a metal hook.
