I craft and use them to store extra fine glitter, sequins and pieces of polymer clay. I find this to be the most convenient size for my items, especially when storing. As my use doesn't require liquids I'm not sure how effective they are in that area but I open and close these things about a couple of times a week and I've been doing this for the past 6 months and they haven't done bent, broken, seal lost or something leaked. In addition, these things have been dropped several times, even when in a heavy condition, and have been of the same quality from the first use to this day.
