The 'Carball' from Black Leaf® is an activated carbon adapter for bongs made of borosilicate glass for filtering the smoke. The adapter, here designed as 'Skull', has to be filled with activated carbon and then placed between the chillum and the bong bowl. The activated carbon filters out a large amount of harmful condensates and tar from the smoke without affecting its effect. The smoke tastes milder and it is more gentle for the lungs. It keeps your pipe clean longer and makes harsh blends taste smoother. Stainless steel screen included.
