Zob UFO Beaker Bong This eye-catcher from Zob Glass is awesome! It stands approx. 14 inches tall. This beaker features a UFO flat disc percolator, providing great percolation. The UFO perc resembles a UFO floating in the middle of the tube. The beaker also has a splash guard and a three-prong ice pinch. A diffused down stem adds another level of diffusion to your smoke. By the time the smoke enters your body, it'll be smooth as fuck! Buy this pipe!! Zob standard 14mm. ground glass slide comes with the beaker. Zob goes to great lengths to make sure every piece is one of a kind, so the label will most likely be different than the one pictured. - Perc: UFO Flat Disc Percolator - Features a Splash Guard and Three Prong Ice Pinch - Height: 14.00 inches - Base Width: 5.00 inches - Glass Thickness: 5.00mm. - Tube Diameter: 50.00mm. - Down Stem: 7.00 inch Diffused Down Stem - Slide: 14.00mm.
