This 6 arm diffuser downstem is perfect for anybody looking to turn their bong into a high tech, scientific bubbler
The six arm honeycomb percolated diffuser optimises the diffusion of the smoke by passing it through multiple slits on each arm of the stem. This in turn increases the surface area of the smoke, allowing for ultimate cooling and filtration
This stem will work with 18.8mm bongs that require 7.5cm stems, and will contain any 18.8 ground glass bong bowl
