Identifying OEM toner

[Mohamed Mesbah]

Hi guys, i need help identifyng OEM toner.
Boxes are the same but toner bottles have some slight differences between them.
Both suppliers claim that THE TONER IS OEM.
Are these differences common between bottles or not.
Any help is appreciated. Thanks in advance.

They were made at different factories during the shortage. All I can tell you is if it has the blue kon/min moon it's OEM. I've seen aftermarket boxes look almost identical but never the blue moon on box or label on btl cap.
