Black Leaf Glass Bong - Kooler works much in the same way as a bucket bong, but this one is a lot nicer.
Taking away the hassle of having to fill up the chamber by breathing in, is now replaced with one smooth pulling action and then just a gentle release to expel the smoke.
Even if this ends up being a party piece, it looks so great it's a must have for any glass collector!
Works wonders!
