Grace Glass | OG Series | Recycler Green Glass Water BongThis approx. 13 inch bong is hand blown by Grace Glass in Amsterdam with style in mind. The design features an inverted sprinkler percolator in the base and 6 channels that circulate water throughout the two chambers of the bong. This recycling of water coupled with the filtration from the percolator combine to make some super smooth smoke. Grace Glass added green accents to the mouthpiece, percolator, and base. As is typical, their logo is included
