This hand pipe by Mathematix features a life-like grenade. The bowl and handle of the pipe are black and the chamber is made of brilliant dichro teal glass. The hammer design and flat bottom allows this bubbler to stand on it's own. The fixed downstem provides excellent filtration and function. The only thing this piece will blow is your mind when you smoke out of it. A must have for fans of FPS shooter games! Made from thick borosilicate glass by Mathematix.
