We used them to hold all the itty bitty plastic character figures our DD collected on our last trip. She went nuts over those things and wanted every set she saw. But once out of the box, those things end up scattered everywhere. A quart size ziplock turned out to be just big enough to hold a set (usually) and kept all the pieces of each set from getting separated.
but I made them to share, and share we did!
I specifically put em in these baggies so theyre shareable, easy access in my backpack, dont take up much room at all and we had no prob giving a bag away to kids who didnt want to give our crayons back.
. ziplocks you could use for almost anything. For example any snacks for on the go.
