I have a question for anyone who works at a dealership. When one buys nuts and bolts online that are sold as "Genuine Volvo" are they always individually bagged in the sealed Volvo bags?

I recently ordered some nuts, bolts etc from an online vendor and they were sent to me in a non-Volvo baggie with handwritten part numbers in magic marker on the bags and no Volvo markings. How can I be sure they really are genuine?

 

They put them like you got them alot of the time. I get them like that all the time at the shop I work at.
