With the simple yet innovative design, each user is able to control how air flows in to their mouth alongside the vapor. Product Description The self-containing design is based off of our venting system. Each ring has a slight outward angle so when you pull out the ring, it adds more resistance by closing the gap. When a ring is pushed in, a small amount of air is let in through the crevice. The ability to instantly change the impact of the vapor's heat on your lungs and throat, has proved to make a big difference to our customers.
