This Boost Wave Glass Bong is an impressive piece of glass art that will blur your senses! It is made of a solid heat proof borosilicate glass formed in the shape of a yellow bubbly base tube. A detachable diffuser with a sure ground of 18.8mm diameter is used a means of spreading your smoke into the tube in order to get filtered by the water. The sure ground connects to a yellow fumed bowl on top of it for placing your herb or tobacco. In addition, a kick hole at the height of the socket offers you the option of enjoying a different pull angle! The whole set-up ends up in a slide mouthpiece ring for a more pleasant flavor.
