Zob OG Beaker Bong This beaker from Zob Glass will all your basic smoking needs. It's approx. 18 inches tall, and has a nice, big beaker bottom to fill with smoke. The diffused down stem adds percolation to the water, giving you smooth hits every time. For extra chilled rips, this pipe has a three-prong ice pinch, allowing you to load it up with ice. This pipe takes a basic beaker and turns it into a stylish functional everyday piece! As with all Zob tubes, this one comes with a 14mm ground glass slide. Zob goes to great lengths to make sure each piece is one of a kind, so each label will most likely be different than the one pictured.
