This double glass recycler by Black Leaf measures 23cm (9 inches) in height and is especially designed for smoking herbs. This complete set is equipped with a built-in slit diffuser and a 14mm female glass herb bowl that fits on the 10mm male joint.
This Black Leaf bubbler has an inline-slit diffusor and 2 recyclers where water is additionally swirled during smoking. While the water is drawn through the tubes and then flows back into the main chamber, harmful substances get stuck at the wall. This to ensure a smoother hit that is very easy on the lungs and throat, but still packed with flavor.
