Custom Marni Schnapper mushroom valves
Approximately 11-12mm OD, 30mm overall height, stem 6mm at the widest, concave. Fits most slurpers.
The concave stem is not just for appearance, it changes the speed and placement of your oil, accelerating at the widest part of the pillar and prefering the concave portion for expansion/vaporization. Based on the same "hourglass" principal we have been using on pillars, these afford small, subtle overall improvements. These pillars will work best focusing a little extra heat around the narrowest portion of the pillar where the oil will spend more time.
