Durable Big Bong Bowl
A Caldera is a lake made from the hollow that is leftover from a volcanic eruption. GRAV likes to be really fancy with all their product names so they didn't give much away with the title of this bowl. The point is that its a large 14-millimeter bong bowl that can carry a ton of weed. If you want to get yourself and some buddies stoned on one big bowl or go straight to the moon on one giant hit then this bowl will get you there and you can get it in the color that you like.
This thing is designed very well, it just sucks herb and burns it all, you won't have unburnt weed at the sides of the bowl, and it rips like a ************ the size of the hole is perfect not too small, not too big.
Fits well, burns evenly, and the hole at the bottom is sized well.
Worth the buy!!
