I may have acquired a number of small pieces of paper and am trying to plan a weekend with my friend. I've got a total of 8 now, but I'm unsure if 2 of them are still good. I've had them for about a year and wasn't aware until recently that heat could cause degradation. I'm not sure how much they may have lost in terms of quality, but I've got enough that it'll be fine. Looking forward to it.
