This glycerine filter is the best wy to upgrade your bong if you want to experience big rips of cool smoke. It's amazing!
I'm new to glycerine but after using this filter a few times, I've fallen in love. Thanks to DopeBoo and its customers for opening my eyes to this new experience.
Nice add-on if you want the ultimate smoking experience out of your bong. Glycerine really can make a difference if you can't handle harsh hits.
