I bought one of those plastic needle organizers - and for some reason I thought it would have a 'sizer' on it for needle sizes like the knitting needle guages have - and I thought it would have a magnifier so I could read whatever was written on the side of the needle.
I already had a lot of needles that I had stuck in a piece of cloth and I thought it would help me decide what they were.
As it is - I can tell the ones with burrs on them - they get discarded - and the really thick ones from the finer ones.
