This self-extinguishing smokeless ashtray fits the majority of standard cup-holders. There's no need to snuff out your cigarette butts, just drop them in and the smoke is trapped inside while a lack of oxygen stops the cigarette from burning.
Wait an hour or so after dropping in the last butt before emptying ashtray. To empty just remove the lid and dump contents.
Spectacular little ashtray. I have a truck but there are no windows in the back so my friends use to throw a fit about not being able to smoke when we went out together, this made all the difference.
