from my understanding, an obi is a very particular thing, mostly (if not only) seen in the Japanese market, and typically has price codes, bar code, and much more (example)
I’d probably enter this as ‘other’ with a comment like ‘band around packaging’ or something?
I actually forgot book belly-bands/wrap-around bands are also called obi in Japanese, and that’s probably where it comes from, but… we don’t call them obi, do we? My feeling is that in English “obi” is only used to refer the Japanese strip around the spine that almost unique to Japan. I think the question isn’t so much what do the Japanese call obi, but do we call obi. What is the obi tag for, that Japanese-style strip of paper around the spine, or any strip of paper around the case?
I actually don’t know and would accept whatever the consensus is, but the wiki definition should be updated if we wanted to be more than the “strip of paper around the edge” thing.
