Display packages include a packaging including a cavity for holding an item, and a trap seal card including a first opening. The trap seal card retains the packaging such that the item held within the cavity is visible to a consumer through the first opening, and a portion of the packaging protrudes through the first opening. The trap seal card includes a front panel integral with a back panel. The packaging is between the front panel and the back panel. Blanks for the trap seal card include the back panel or the front panel having a first length and a second length less than the first length. The first and second lengths extend in a perpendicular direction to a first fold line. Blanks for the display box include a tab detachable from a remaining portion of the back panel when the back panel is separated along a ninth fold line.
