Never has a bong this huge been so inexpensive. Made with thick clear glass, the Double Inset Honeycomb to UFO Perc Bong w/ Ice Catcher is fully functional and sturdy. It features three total percs; a double inset honeycomb perc and a UFO perc. All three percs do a very good job filtering your smoke before it reaches the ice catcher. This ice catcher holds ice and cools the smoke before you inhale. The flared mouthpiece offers a comfortable, airtight seal so you can take huge rips. Pack the 18mm male deep bowl and insert it into the 18mm female joint, which is supported by a Dewar's joint.
