Yeah, not the subject you were expecting, eh ?! Canon only makes 12mm and 25m tubes and each costs about $180US/each. Must have gold in them.

I paid $180 for the set of 3. It is labled for the camera dealer network in my region but I think it is manufactured by Tokina. The Kenko tubes seem highly recognizable in these forums.
