Packaging Design Wishbhone Product-Packaging Integration by Packlab The intelligent one-piece structure folds in on itself and the diecut hole provides an inner slot mechanism that keeps the product in place. The structure continues to fold in on itself and eventually locks to create a pack that resembles a display case. The packaging has been designed to work effortlessly and make sure the product is given a hero status. The unique hidden euro hook provides an additional optional retail function, however this can be hidden to allow the product to stand on its legs in a premium retail environment and look less like a commodity.
