I use the colored ones as pocket squares and the white ones as handkerchiefs. I wear lots of blues, so these worked really nicely for me. They match just about every shirt and sports jacket combo I wear. They are on the thin side, which for a pocket square isn't good. But these are handkerchiefs that I try to make believe are pocket squares. And because they are thinner, they aren't big and bulky when placed in my pants or even in my inside jacket pocket. I bought the Assorted Set 001, but now I am looking at getting the set that is all purple. And probably some more plain white ones too.
