This 4-piece pipe is cunningly constructed and simply demands that you play with it.
The bolt end unscrews to become the pipe bowl and the inside of the bolt screws out to become the mouthpiece.
And the nut? The nut is just a nut.
This pipe is just like the stealth pipe above being made from metal parts giving it the ability to hide in your toolbox without being noticed.
