Abstract
Abstract An enclosure for storing one or more keys in singular compartments, said enclosure being sized and shaped as a conventional credit card but used as a business card with the business card information printed on one side of the enclosure. The enclosure is planar shaped and rectangular and includes a clear, plastic face having one or more slits, which are appropriately sized for permitting the insertion or removal of a key through the slit into the enclosure. The enclosure may further include a diagonal heat seal which seals two flexible sheets together to form two separate compartments, one for each key. An alternate embodiment can accommodate up to four keys with two on each side, utilizing four separate key compartments with a slit in the exterior wall for access to each compartment.
