I've got to tell you...I love the snack size Ziplock bags! I find myself using them much more than the sandwich size, or quart size bags. They're especially handy for leftover grated cheese, chopped onion, lettuce, and grated or diced veggies. I most recently used a snack bag to put small nails and screws into for safe keeping while I painted a room. When my grandson comes over, he likes to eat jellybeans so this is a perfect size for him to tote around and have a snack. Today jellybeans, tomorrow goldfish crackers!
I'm always on some kind of diet so the Ziplock snack size bag is perfect for small half sandwiches, and you can't pack as many chips in this smaller Ziplock bag. Good for the waistline!! When I travel I pack my jewelry in them as well as my memory sticks for my camera. I think the bag could be a little thicker for durability, but otherwise it's fine.
By now you get the idea. I know the other sizes in the Ziplock line are versatile too, but the snack size is just what is needed for all the teeny-tiny chotchkies you want to stash...oh yeah, and food items too!
