OK is a really solid set of high-quality cotton handkerchiefs that are very skin-friendly and the fabric takes a big step forward. from the boring white handkerchief that most people still use. After about a month of use I would say they are holding up well except after washing and drying the fabric has shrunk a little more than I expected. Suffice it to say, and it has been consistent across the range up to the point where I mention it.
