Multiple layers of glass is what gives the Nucleus Ladder Accented Hammer Bubbler its distinct look. Inside of the chamber is a showerhead perc, which is directly connected to the 18mm female joint. With only a small amount of water needed this perc will diffuse your smoke for a much smoother taste. The Ladder Accented Hammer Bubbler is able to stand on its flat base and mouthpiece. The convenient shape of the mouthpiece makes toking a breeze.
