it’s so handy. 99% of the time I use it to clean my glasses, but if I’m with someone who’s crying, if I need to clean off a screen, if something’s dusty or gross but I need to pick it up, if I get sweaty and need to wipe my brow, if something gets spilled and there are no napkins handy, etc I can use it. when my dad passed I got all his; he was a high school principal most of his career and carried one every day.
