A label for a package that includes a base layer and a top layer attached to the base layer is disclosed. The base layer includes a central surface adapted to receive written markings. The top layer covers at least part of the base layer and includes perforations such that a detachable part of the top layer has a perimeter at least partially defined by the perforations. The detachable part includes a front surface and a back surface that faces the base layer while the perforations remain intact. The front and back surfaces of the top layer are adapted to receive written markings. And, the top layer is opaque such that while the perforations remain intact, any written markings on the back surface of the detachable part or on the central surface of the base layer are not visible from a vantage point outside of the label.
