Black Leaf - 8-arm Tree Perc Precooler - Blue - 18.8mm
This new precooler from Black Leaf features a slitted, reinforced blue glass 8-arm tree percolator, allowing you to add luscious, bubbly smoke diffusion to any bong with an 18.8mm joint! Use with any 18.8mm bowl, but please note that this precooler does NOT come with a bowl. The chamber features the Black Leaf logo and is 50mm wide, giving your smoke a chance to break up and cool down before even reaching the main chamber of your water pipe.
