Spaghetti measure

Spaghetti measure or spaghetti measurer? Answers on a postcard. 

I seem to manage judging how much spaghetti to cook by grasping a random amount from the packet, but if you would rather be a bit more precise, we've got these. Like teapots sizes, though, I suppose it's a bit subjective whether you agree with what the measure says in terms of enough pasta for 1,2,3 or 4 people...

They're a very pleasing object though. I would be inclined to hang it on a nail by the cooker.
