I use the quart-size, slider storage bags on a daily basis. I fill them with grapes, olives, strawberries, and cheese sticks to make our daily snack bags. Every Sunday I make ten of these for the week so that each morning all I have to do is take two out of the refrigerator, one each for my husband and I. Then we can eat our snacks throughout the day while at work. Very convenient and, of course, love the slider and flat bottom!
