Abstract: A package (200, 201) includes a pair of finger tabs (210, 212) formed on sheets (202, 204) that are used to enclose a sterile bandage (206) and that can be easily gripped by fingers and then pulled apart to expose the sterile bandage (206). Each finger tab (210, 212) and sheet (202, 204) is substantially identical in size and shape to provide uniformity and ease of manufacture. Finger tabs (210, 212) are positioned off-center at the end of sheets (202, 204) so that a complementary finger tab and sheet can be positioned facedown with the single finger tab positioned adjacent to the complementary finger tab, yet the finger tab is exposed without interference of the complementary finger tab to provide for ease of opening of the package. Both finger tabs may be located at the same end of the package (200, 201).
