This is beaker from Zob Glass is part of the micro family of pipes. They're made from 38mm tubing. It's approx. 14 inches tall and is 5mm thick. This beaker features the Zob UFO perc. It bubbles like a fucking champ! The diffused downstem adds another level of percolation to your smoke. It also has a splash guard to keep water from splashing into your mouth. It comes with an 18mm ground glass slide. Zob goes to great lengths to make sure each piece is one of a kind, so the label you receive will most likely not be the one pictured.
