I've had these handkerchiefs for a least a couple of months now and am quite satisfied with my purchase.  I have seasonal allergies and hate pulling a white handkerchief out of my pocket when I'm sitting in meetings.  These colors are much more discreet.  I've read reviews that said they were too thick, too thin, and too stiff.  To me, the thickness is just like any other new handkerchief I've ever purchased.  When they were brand new they were stiff like any other new mens handkerchief, but after three or four washings they were just fine.
