How to distinguish an original HP Q5949X cartridge from a fake?

Question

HP

Hello.
Today I was puzzled by a friend that the cartridges that one company supplies to us at a rather high price tag are fake. He motivated this by the fact that on the side (highlighted in the picture) the plastic is sealed on the original, and on the fakes there are bolts.
Help me find out the truth, because the cartridges cost like a cast-iron bridge, but they look very original: a thick cardboard box, a hologram, barcodes, air packaging.

Answer 1

Insert into the printer, it will say.
Or contact HP technical support, and do not listen to Vasyanov.
