Powerful glycerin coil that fits on any of our Bongs or the Recycler Bong. It's the largest glycerin coil we make (same size as the Bong XL's) except instead if our spiral coil it's a straight tube. While not quite as cold as the spiral style, the straight tube style is easier to clean and a ton of fun to use. 

Fits:

All bongs and Recycler Bong
