The Pipe One is a glass pipe enclosed in an aluminum casing making it virtually unbreakable. Made up of two (2) main pieces, the Pipe One can easily be disassembled for maintenance and cleaning. A regular pipe screen can also be placed inbetween the two (2) main pieces to prevent any backflow of unwanted material towards the user. This is definitely our go to pipe and we highly recommend trying it out. It is available in green, red, blue, black and purple. Comes with extra pipe screens, pipe cleaners and O-rings.
