Ultra-thick glass, amazing percolation, and a clean design – what more do you really need in a great bong? This piece is constructed with durable 7mm borosilicate glass, and stands at 15 inches tall. The chamber houses a matrix percolator which has tons of diffusions holes to filter out impurities and cool down smoke. The unique zig-zag in the neck not only looks awesome, but it also acts as an ice pinch to throw in a few cubes, and the extra neck length itself aids in coolness! The Biggie Zong is heavy and sturdy, with an extra-wide base for great stability. It's fully clear for a minimalist look, with a light pop of color on the mouthpiece.
