Zob OG Beaker Bong This beaker from Zob Glass will all your basic smokingneeds. It's approx. 18 inches tall, and has a nice, big beaker bottom to fill with smoke. This beaker is made with 9mm thick glass instead of the standard Zob 5mm glass. 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.
