The click pipe is an interesting rethink, using magnets to hold the two parts together. When closed it looks like a little block of aluminium, but it opens up with a nice little "click" to reveal a 10cm pipe. The advantages of this pipe over other small pipes is that because of its two peice design held with magnets, the mouth peice doesn't overheat burning your lips, the other is, when you close the click pipe the bowl is covered, meaning it won't stink out your pocket and drop all the crud in there too.
