Clear glass Beaker Based Bongs can be found just about anywhere one shops for Pipes but not all of them are Billowby approved. The simple, clean lines of this Bong make it perfect for everyday use. Obviously, the more arms you have in a Perc Bong, the smoother your smoke will be. This 14-inch Water Pipe has all the bubbles you need with the swirling power of those four arms, and once you've given it a try, it has "new favorite" potential written all over it. Adding this big boy to your collection is a plus you won't regret.
