Grumpy Percolator Pipe - Black Leaf
The Grumpy by Black Leaf combines a bold, humorous design with serious engineering. The bong is made entirely of coloured borosilicate glass and shaped like a grumpy face, which instantly makes it an eye-catching piece. Once the lift-off bowl is filled with aromatic herbs and you light up, the character really comes to life.
The built-in percolator splits the smoke into small bubbles and guides them through the water, for a cooler and smoother draw. At a height of 200 mm this is a compact model that is ideal for the road. The joint is SG14 (14.5 mm), the common size, so you replace the bowl easily.

Use and cleaning
Fill the bong with water until the percolator sits just below the surface and place the lift-off bowl. Light while drawing through the mouthpiece. A percolator needs a bit more attention when cleaning: rinse regularly with isopropyl alcohol (at least 90%) so the small openings stay clear. Borosilicate glass is strong, but still breakable.
