Disclosed is an advertising package that consists of two trays that are hingedly attached along a longitudinal and transverse axis. One tray includes two compartments formed from substantially rectangular shapes to allow inclusion of items that are not distinctive in shape such as a coin, key or the like. The compartments are depressions which eliminates the need for upstanding side walls and the need for a circumscribing channel or coupling passageways. Printed material can be placed on the entirety of the first tray which provides a background to the compartments and allows viewing through the package sidewalls. The package is constructed and arranged to be sent as non-machinable flat through the United States Postal Service (USPS).
