I got these to use in the garage since it looked like they'd work even if humidity got involved. They do work through the heat of a summer in a garage, even a super wet one like we seemed to have (I had to get more damp remover pouches than I usually do). I did not use the twine in the garage, again humidity, I used zip ties to make a loop for them to hang off of, and they work perfectly. I drilled two small holes next to each other on my bins, so I'd have somewhere to hang them, and now I know which bin is full of sleeping bags, and which is holding the holiday decorations, without having to open the lids to check, or work out what the faded sharpie marks used to say. I'll be getting some more since I have a few more bins and containers I'd like to label.
