They Hoyo band on the left looks very fake to me, the one on the right is harder to tell but that also looks fake.
Yep. This was a pretty good tell, Chuck. The other problematic elements were the hologram sticker on the lid, the box code font, and the "Comintur" stamp on the box bottom. Oh yeah, and the puke lime green color of the seal ink.
As for the black light, you should be able to see a "watermark" coat of arms that comes across as yellowish.
Or pinkish, or yellowish-green.
Also, the serial number numbers should remain red but the 2 character code preceding them should be black (or very close to it).
Not necessarily. Some serial numbers will not glow red but remain blackish.
