Sphere Base Bong


These mini bong's feature a rubber grommet joint as opposed to frosted glass

The main feature is a rubber grommet which tightens the bowl with the bong. Rubber grommet bowls are made as one piece, so the bowl is fixed with the stem.

It is good to lubricate the rubber with silicone oil occasionally to preserve flexibility and ensure that the stem will be easily detachable. Be careful when pulling the downstem out of a rubber grommet bong, use a screw motion and pull. Bear in mind that it is glass, quite fragile material.
