Pop up foil sheets are individual sheets of Reynolds Wrap aluminum foil. Wrappers are so easy to use with all your foods because they pop up 1 at a time and require no cutting or tearing. Use them for wrapping food to go, as portable place mats, wrapping sandwiches, protecting counters during meal preparation, when making snacks, or to store food in the refrigerator. 50 foil sheets per box.
