Black Leaf - UFO Perc Precooler
This new precooler from Black Leaf features a powerful showerhead percolator, allowing you to add luscious, bubbly smoke diffusion to any bong with an 14.5mm joint! The top joint fits an 18.8mm bowl, but please note that this precooler does NOT come with a bowl. When you inhale, smoke travels through the UFO perc and is then forced through the stem into your bong, giving the smoke a chance to break up and cool down before reaching your throat and lungs. The Black Leaf logo is applied on the chamber in black.
