A stylish bong reminiscent of a thermos in its design will keep water cold for up to 12 hours. The bong is equipped with a double-wall vacuum-insulated stainless steel base and neck, an unbreakable aluminum bottom stem and a borosilicate glass bowl. The product has been created to be extremely durable while being as easy to maintain as possible. The bong simply pairs with all DynaVap vaporizers. VonG (i) and 'B', only type 'M' and Omni will need an adapter. The stainless DynaVap bong is the right choice for anyone looking for a reliable hookah that is just as durable as it looks.
