This is a rather strange comment, Sharpies are permanent markers that aren't designed for whiteboards. Nor do they dry out, I've had Sharpies last multiple decades. Are you thinking of something else, perhaps? The benefit of Sharpies is that you can mark most surfaces with them and its permanent. NASA uses Sharpies because they can be used in zero gravity. I suppose you could use them on paper but it's likely they'd probably bleed thru.
