The Classic Beaker Big Perc Double Stack is Prism's version of the classic beaker single perc bong with a larger middle perc, and let's face it, it's beautiful. With our system, it's easy to break down to just a classic beaker and it's also easy to clean and throw in a backpack for an adventure. 

All together, this set up comes with a Standard Mouthpiece, the 7mm Classic Beaker Base, a 12 Stem Big Perc, an 18mm joint, and then the downstem and bowl. It also comes with your selected aluminum clamp. The clamp is made of an aluminum exterior lined with a specialized rubber interior, along with a lever on the side to close and tightly seal the two pieces of glass together. On the interior of the clamp, there is a built in rubber gasket ridge where the two pieces of glass butt up against making a very safe and secure seal.
