The Recycle Black Leaf Oil Pipe has got a height of 19cm and, as its name implies, has got a recycle function. The quality of the water is improved by augmenting it with fresh oxygen. First, the hole diffuser neatly swirls the water, before it flows into the second chamber and then back into the main chamber. The pollutants laterally distribute at the bong.
Oil dome and oil pan are included. The latter can only be heatened at the peak, because otherwise the cut breaks.
Diameter (tube): 5mm
Diameter (soil): 8cm
