Bought these for my 11 year old son who suffers from allergies. He had a terrible habit of wiping his nose on his shirt sleeve. BLACK! He started using the handkerchief like a fish in water. He didn't use disposable wipes because, according to him, they burned his nose and teared it from friction. Now he puts a clean handkerchief in his pocket every day and uses it even when I'm not around so I can tell him.
