A clear plastic package has an upper piece and a lower piece, each piece having a generally rectangular configuration, and the lower piece having front and rear edge portions, and opposing side edge portions. Along each edge portion of the lower piece there is a pivotable wall attached by way of a living hinge, and these walls can be rotated from a generally horizontal position to an upright position relative to the lower piece, and there is a longitudinally extending locking edge on a lower part of each wall that resiliently snaps into engagement with a cooperating fixed edge on a projection that extends longitudinally along the perimeter of the lower piece, when the walls are rotated to their upright positions, to hold the walls in their upright positions. The upper portion of each of the walls is so shaped that when they are in upright position, they cooperate to provide a recessed ledge. Extending along the perimeter of the upper piece is a downwardly projecting rib that is received within the recessed ledge of the lower piece, and adhesively secured therein to form a sealed enclosure for an article.
