This beast from Zob Glass has it all! It stands approx. 17 inches tall. This beaker features a fixed flat disc diffuser that provides crazy diffusion. If that isn't enough, a low profile UFO percolator sits above it, adding an extra level of cooling, filtering percolation. The pipe has a splash guard and a three-prong ice pinch, so you can pack the top of the tube full of ice and get extra chilled rips. The glass is 5mm. thick and proudly made in the U.S.A. Like all Zobs, it comes with an 18mm ground glass slide. This piece is the total package! Zob goes to great lengths to make sure each piece is one of a kind, so the label you get will most likely be different than the one pictured. - Perc: UFO Percolator and Fixed Mini Flat Disc Diffuser - Features a Splash Guard and Three Prong Ice Pinch - Height: 17.00 inches - Base Width: 5.00 inches - Tube Diameter: 50.00mm. - Glass Thickness: 5.00mm. - Slide: 18.00mm.
