After a year using only these masks for work, I can easily say that they're the best! Last year I bought 6 for work and would wash the lot by hand in lukewarm water with mild detergent once a week. After roughly 52 washes, they were still soft and efficient but looked less shiny (normal for silk after constant washing, even when gentle). So this year I bought another 6 for work to refresh my look! My skin is comfortable (no mascne or too warm or moist) and the masks fit like a glove. Shipping is fast to eastern Canada and always arrive neatly packaged. Thank you again for creating such a life saver product!
