This Boost Bolt Glass Bong is an impressive piece of glass art! It is made of a solid heat proof borosilicate glass, formed in the shape of a curved base tube. The special feature of the Bolt glass line will make your bong more comfortable to grip and more funny to smoke. You can place your precious herbs or tobacco onto a red fumed bowl, which connects to a chillum through a sure ground of 18.8mm diameter. The smoke enters the tube through the chillum, so as to get filtered by the water. In addition, some ice notches will hold a few cubes, for cooling your smoke, and a kick hole at the height of the socket offers you the option of enjoying a different pull angle! With the white Boost logo featuring along the tube, the whole set-up ends up in a comfortable mouthpiece ring.
