The MJ420 Glass Blunt is one of the newest innovations in the smoking industry. With the rise in popularity of glass blunts, the MJ420 was created to make the perfect one. The thing that sets the MJ420 glass blunt aside from any other is it's unique adjustable size. The main body features "steps" that allow you to pick a size for the glass tube to extend. This is helpful for those who may not want to load a full blunt. Additionally, as you smoke, you can keep ajusting the tube to a smaller size so that the ash is easily ejected. The MJ420 fully disassembles for easy cleaning and is available in a variety of colors.
