AWZ1287,
I currently have a NIP discontinued G2L sitting on the shelf, and the only thing "sealing" it is a single piece of scotch tape, wrapping around the bottom edge of the packaging. In my case the the tape finish is gloss, not matte. There is a barcode label on the back which the piece of tape is underneath. You might want to look for a barcode label going "over" (applied later) the piece of tape. My piece of tape is not applied extremely evenly, or extremely perpendicular to the bottom edge of the package.
