1. A package comprising:
a thermoformed thermoplastic blister having a protruding front product bubble with a peripheral flange which extends outwardly from the front product bubble, and a front extraction tab which extends from the front product bubble;
portions of the blister defining a back product bubble with an outwardly extending peripheral flange which adjoins the front product bubble flange along a hinge;
wherein the blister is folded about the hinge to bring the front product bubble flange and the back product bubble flange together so the flanges overlie one another and define a closed product compartment interior to the overlying flanges for retention of product therein;
a front card having an outer perimeter and having an exterior surface and an opposite interior surface, portions of the front card defining a bubble opening having an inner perimeter;
portions of the front card bubble opening which define a tab front access opening which extends from the outer perimeter of the front card to the inner perimeter of the front card;
a back card having an outer perimeter and having an interior surface which is connected to the front card interior surface, and an opposite exterior surface, wherein the back card has a rear product opening through which the back product bubble extends;
wherein the overlying blister flanges are retained between the front card and the back card so that the front product bubble extends through the front card bubble opening, wherein front product bubble peripheral flange and the back product peripheral flange are not adhered to the front card or the back card, and wherein the back product bubble underlies the entire front product bubble, and thereby closes the product bubble such that a volume for retaining and displaying a product is defined between the front product bubble and the back product bubble;
wherein the front extraction tab extends outwardly from the front product bubble and has a front surface and an opposite back surface, wherein the front extraction tab extends into the tab front access opening and is not overlain by the front card, such that the front extraction tab is free of the front card and extends beyond the outer perimeter of the back card to be accessible at both the tab front surface and the tab back surface without being blocked from access by the front card or the back card for gripping by a user to engage and remove the blister from the front card and the back card; and
portions of the back card defining a notch along the outer perimeter of the back card which forms a tab back access opening, wherein the front extraction tab extends into the back access opening of the back card.
