A card and blister package for small articles of commerce has a clear plastic blister piece, a card and a retainer piece. The blister piece had an article-receiving cavity and a flange extends along the upper edge of the cavity, and pluralities of upwardly extending locking posts are spaced apart along the flange. The card has openings for receiving therethrough the locking posts and the retainer piece had a plurality of integral downwardly-opening locking caps spaced therealong, whereby when the posts are engaged through the card openings the caps can be snapped into locking engagement with the blister posts so as to secure the card to the blister. Each cap is encircled by an arrangement of perforations, so as to detachably connect the cap to the retainer piece and whereby twisting of the cap will cause it to shear free of the retainer, and rotation through about 90 degrees will cause the caps to unlock from the posts, allowing the package to be opened.
