Just wondering if anyone else has a bunch of these laying around. I stocked up a little ways back and keep them in a dry and cool place but I was wondering how long they would stay "good" since they seem a little harder to find lately. Anyone else have a pile of these and ever have them go bad or anything like that? Mine seem fine since last time I used them but it's one of those "Hmmmm" things that comes to mind now and again.
I stockpile them too. Hangzhou is very humid, and I have noticed that after about a year or so sitting on my work desk, they don't want to come off of the backing. I think if you keep them cool and dry they should last longer.
