A male slide piece for a bong that adds a second water filtration. A mini bubbler that slides in and out.
My bong hits too hard, I need to get an ash-catcher.

An attatchment for a bong that slides into the diffuser containing another water pool and downstem to catch the ashes. Keeps a real smokers pipe clean for longer by never letting the ashes touch the tube.
Dude my new ash catcher is the SHIT!! I havent had to clean my bong in a month!
