Swiss Army Pipe
This is one of the coolest pipes ever, it can do it all, just like the name implies. These pipes consist of a tube with a bowl at one end. There is an opening at each end of the piece, with the one nearest the bowl serving as a carburetor. The extra chamber allows the smoke to cool even further. These are intended for the experienced users, as they definitely take skill to use. Measures 16cm long when assembled.
