The ‘Carball’ from Black Leaf® is a bong adapter made of borosilicate glass for filtering the smoke. The adapter is filled with activated carbon and then placed between chillum and bowl.
The activated carbon filters most of the harmful condensates and tar from the smoke without affecting the effect. The smoke tastes much milder and the lungs are spared.
In addition, the bong stays clean longer. Stainless steel screen included. With pattern in various neon colours.
Attention: Please clean the outer coated parts of the bong with water! Do not use aggressive detergents or scratch it with sharp objects!
