These headbands are the best we have come across so far, and it’s honestly sad that their ratings are being brought down because of people complaining that they don’t do what they’ve never claimed they would do.The package clearly states disposable, as in like disposable, garbage after one use, so no, I would assume they wouldn’t wash well? They’re meant to be disposed of, not washed.Anyway, great handbands for anyone looking for disposable headbands, these are it.I wonder how well their disposable masks hold up in the wash lol
