You know what you’ve bought, so you already know what clues to look for. Let’s say you’re a luthier who’s been given a guitar to fit and cut a new nut on, and been given a packet of those strings. Whilst you might guess 10-46, you’d want to be surebefore selecting appropiate nut files. And there’s no clue as to the intermediate string gauges, so you’d need to go on line and look them up. It wouldn’t take much to make the sticker slightly bigger and add a line that said 10-13-16-26-36-46, which should be pretty clear to snyone.
