I don't use them, but HE uses them and HE loves them very much! What I like is that they are so "modern" than your grandfather's handkerchief. There are enough color options in the set so you always have the right one. I machine wash them and usually line dry them, but I put them in the dryer. I don't iron them, I fold them and smooth out as many creases as possible. They're good for something to keep in a pocket. The quality is very good; The stitching is holding up well and seems strong. I'm so glad I stumbled across these!
