The Chicago Lighthouse is a nonprofit organization that helps people who are blind and visual impaired. One of their products they've developed is a lens and screen cleaner that required special packaging to stand out in common retail settings. Not only was the product label considered, but the box that the product ships in was to be used as the shelf display as well.
The lens cleaner comes in a full size bottle and a travel size pack. Below you can see the product labels for both products and how they fit within the assembled display box.
The display box ships as seen below, with the product inside. To utilize the entire surface area of the box, the instructions for how to assemble the display box are printed on the tear away section of the box.
