DEA' Mini Beaker Bong
This cute little beaker bong is so small you can pretty much just throw it in your pocket before you go out. It's about as simple as Black Leaf could make it and gives a great experience hit after hit.
The beaker base gives plenty of capacity, the joint is a 14.4mm female ground glass one and they include a 14.4mm male slide bowl with roll stop to finish the set off. They even gave it a carb hole for when you can't be bothered to pull the bowl when you want to clear it.
