This impressive beaker bong is for the smokers who need all things BIG: Big bong, big clouds, and big percolation! At 18-inches-tall and crafted from high-quality 7mm borosilicate glass, this piece is large and heavy, making it the perfect showstopping display bong and extremely durable. This beaker is made up of three chambers, each housing their own matrix percolator. Matrix percs are some of the best in the game, offering the most top-notch filtration power due to the high number of openings for smoke to escape and be cooled. With three times the cooling power, you can expect exquisitely-chilled hits, not matter the size! To top it all off, you’ve got an ice pinch, a splash guard to prevent water from shooting up, and a huge bowl piece with a grip! The Optimus truly takes the smoking experience to the next level.
