Black Leaf Double Filteration Bowl 'Cool B'
The Cool B is the latest innovation to come from our friends at Black Leaf. This bowl offers a new, state of the art double filtration system, which uses two percolators incorporated in the bowl design. The benefit of the double perc is that the smoke is filtered as soon as it leaves the top of the bowl and again once it is in the bowl.
This Cool B double perc bowl is a superb filtration system and can even replace bong percs meaning if you own a bong without a perc then this is a perfect extension to your favorite bit of glass.
