Big bong lovers look here! This head-turning piece by Prism is called the Big Perc Double Stack Modular Bong and it's one fine water pipe and we'll tell you why. Constructed in the USA using thick and durable borosilicate glass, this 20-inch tall double-tiered modular beaker bong comes apart for easy cleaning and allows you to fully customize the piece to your liking. 

All you have to do is use the black aluminum clamps that hold the bong securely together to take the bong apart. This makes cleaning super easy, plus it allows you to break this big boy down significantly for easy travel and to store it away if you want to keep it out of sight. 

Prism offers a full line of replaceable and interchangeable bong parts that fit this beast as well as the brand's other water pipes. Inside the Big Perc Double Stack is a big tree perc that offers excellent diffusion and filtration of your smoke. There is even an ice catcher built into the upper stack you can use to add some frostiness to the rips you take from the bong's comfortably flared mouthpiece.

Included with the Big Perc Double Stack is a clear glass slitted downstem diffuser and a 14.5mm male herb slide with a handle. If you want to change the looks of this bong down the road, you can do it easily by making the bong smaller, adding some color to the bowl or downstem, or swapping out the base for another with a completely different style. The sky's the limit as far as options go with this modular bong that's built to last.
