The Funnel (or "Phunnel") bowls are designed to increase air flow through your hookah by putting a hole or multiple holes on the raised centre spire. With the holes elevated on the centre spire, this affords the unique opportunity to conserve the natural juices of the hookah tobacco within the hookah bowl itself. Since the flavor is retained, the shisha burns slower, resulting in longer and more flavorful smoking sessions. The Funnel is approx 65mm high with a top diameter of 60mm. The bottom hole has a diameter of 25mm. Design and colour may vary from that shown.
