Love these Q-tips for using with my make-up. They allow you to get in the smallest areas. I mainly use them under my eyelid bottom to get any marcasa that has rubbed off. The tip allows you to get the smallest make up errors.
I have also used them to clean my ears. You have to be careful with the tip and not try to shape it smaller. Because it makes the tip come undone and is no long pointy.
I use these all most every day. They do not leave cotton trails.
