This is 13.8 inches tall straight tube bong with a CFO perc and fat base, made of glass. The CFO perc is a transformation of two honeycomb perc. And honeycomb perc is really good at filtering ash and other particles hid in smoke, functioning with water to get smooth hit from herbs. So with a honeycomb ball perc, the filtering will be more intense and make purer and smoother hit. You can take it outside, using it during trip, or enjoy the happy hemp time at home. There are two colors for selection: amber and green. The mouth, perc and base are all colored. All the bongs are with matched accessories.
