Hefty Calendar Slider Quart Storage Bags are a reliable storage solution for keeping track of your perishable foods and snacks. These quart size storage bags feature a convenient calendar on the front. Simply use a permanent marker and circle the month and day to keep track of when food and other items were put inside. The clear plastic slider bags also feature a white box underneath the dates so you can write and label what’s inside. Hefty Quart Slider Bags have a stand and fill expandable bottom, which helps prevent the slider bags from falling over and spilling as you place fresh fruit, berries, cheeses, and more inside. The patented MaxLock track ensures an extra strong seal and allows the slider to glide effortlessly along the track as you open and close the storage slider bags. For extra reassurance that your storage bags are fully closed, Hefty storage slider bags use a Clicks Closed sound to audibly indicate your slider bags are securely sealed. They are ideal for busy families, home cooks, and meal preppers. Use these clear slider storage bags to stay organized and pack snacks for school or travel.
