A plastic sleeve over an arm on an unopened boxed pair must be new (and random) for o-matter frames. I got the SI Desert Gascan about 2 months ago, and they didn't have the sleeve.
It seems like the earstem cams on the Gascan are back to be floppy again as well. My polished black frame (which I warranty exchanged from a very loose pair) has a very nicely defined detent, while the SI Desert has a loose, but defined detent that flops a bit when opened...if anyone can understand that. Fakes probably will have a half a$$ed cam detent feel on the ear stems.
