This pipe is called "credit-card-pipe", because it has exactly the dimensions of a normal credit-card. It consists of three stainless steel pads and two magnetic foils to put between.
An instruction shows, how to splice the "slices" on one another. The magnetic foils are quite damageable, but on the other hand they really work very well and keep the metal peds together.

This pipe is called "Cooler", for it's mode of operation creates a long way for the smoke, wich makes the smoke cooler and - every smoker knows that - smoother. 

So the Cooler Credit-Card-Pipe can easily hide inside a wallet and can obtain a cool and smooth joy quasi everywhere and anytime.
