Secondary insertion feature for assembled package

The present exemplary system and method relates to a feature upon the exterior of a corrugated package that allows an access secondary to the primary opening feature for the inclusion of sample materials that are added after the package has been sealed at the contents' (e.g., appliance) place of manufacture. The benefits of the invention are reduced unit operations and labor to include sample materials. Additionally, the packaging feature will deter theft of sample materials from the product to the point of sale. The theft deterrence is achieved via a tamper-evident label covering the feature after sample materials have been inserted.
