The Black Leaf diffuser balls are an innovation from the house of Black Leaf. Who loves the cooling effect of percolator bongs and wants to upgrade an old bong is very well served with the Black Leaf diffuser balls. The diffuser balls are easy to fill into a bong and the effect is noticeable from the first puff. The diffuser balls divide the smoke bubbles into many tiny little smoke bubbles. These are washed out and cooled more effectively by the water, and their surface area is multiplied. With proper handling and occasional cleaning, the Black Leaf diffuser balls can be used multiple times.
The diameter of each ball is about 6 mm.
