I've been ordering this same brand of Memorex CD/DVD sleeves for maybe five years. I could deal with the decreasing quality every year. It was always better (thicker paper) than the next major brand or a no-name.This year -- no more. The plastic window was low quality for all 100 sleeves, loud and wrinkly and distractingly reflective with all the wrinkles. I'm so dissatisfied I'm going to return these.Another cheaper name-brand I accidentally bought a year before (also beginning with letter "M") with slightly thinner paper, at least is uniform and has a clear unwrinkled window.
