This thick glass beaker bong is a simple water pipe that delivers an icy cold, filtered hit. The three pinch ice catcher is located in the straight neck of the bong and holds your ice. When you put the ice into your tobacco bong you will experience a colder hit while inhaling through the flared mouthpiece. This results in a less harsh smoke for you. To further filter your smoke, there is a 5" removable 18mm to 14mm diffused downstem that reaches into the beaker style base of the bong. The slits in the bottom of the downstem filter your smoke before it reaches your mouth. The benefits of a downstem being removable are great because it helps with the cleaning process. This removable downstem fits into the 18mm female joint and also holds your choice of a free 14mm male bowl or dome and nail...or both!
