'Black Leaf' Glass Vortex Downstem

The 'Black Leaf' Glass Vortex Downstem is a glass diffuser downstem with very effectively arranged diffuser slits. The result of these diffuser slits is clearly noticeable; it drastically improves the overall bong experience. How? By diffusing the smoke into a "vortex" through the water, the smoke is cooled and filtered very efficiëntly; it makes the bong water do it's job much better. The inhaled smoke is therefore much smoother on the throat and contains less impurities such as tar. 

Instead of buying a new percolator bong, you can also simply replace you current downstem in your bong with a diffuser downstem to increase smoking comfort.

These downstems are available in different lengths. The length is measured from the top edge. It is made of borosilicate glass (also known as "scientific glass" or "laboratory glass") and therefore has a high resistance to changes in temperature and surface damage (such as scratches). Although it is still glass, borosilicate is much stronger than regular glass and much more durable.
