The disclosed systems and methods relate to improved tamper-proof cases for securely storing and shipping products. A case can include a back panel, two sidewalls, an upper foldable section, and a lower foldable section. Each of the features of the case can be manufactured on a single sheet of material. The upper and lower foldable sections include panels having apertures for holding the top and bottom of a product, respectively. The upper foldable section includes one or more fasteners that secures the upper foldable section to the sidewalls. Once secured, the products cannot be removed from the case without showing evidence of the removal. The disclosed systems also provide a tear strip and/or a tear corner that can be used to release the products from the sealed case.
