FlowerPot "B1" Baller Head Assembly
The B1 nut has a groove over the top of the threads to accommodate a 3/4" Titanium screen and therefore is optimized to work with the 22mm Screen Diffuser so the balls are secured inside the sub assembly.
This Head assembly comes with 4mm ruby spheres.
You are now able to customize your experience by using different material balls that are widely available. (Ruby, Sapphire, Quartz, SiC)
Using different size, shape, and material balls will change the flavor and performance of the head.
