The present invention is a pre-cut aluminum foil round cover that is more convenient to use than aluminum foil torn from a roll, conserves a substantial amount of aluminum that would otherwise be unnecessarily thrown away, and covers round containers more safely and effectively than an aluminum foil sheet torn from a roll. The most preferred embodiment is a foil round having a 5 inch (12.5 cm) diameter. The foil rounds can be pre-cut and stacked, thereby eliminating the need for packaging that requires a sharp blade or serrated edge, and eliminating the frustration associated with tearing aluminum foil from a tightly wound roll that is supposed to smoothly tumble inside of a long box.
