Just trying to be cautious here that's all.
I completely understand that man. But I couldn't find Boston Ivy Healthcare on 3M site either but I am pretty sure they do sell authentic material as a) they deal in healthcare products already and b) a couple of people, including my brother bought and received authentic stuff from them.
Sometimes some companies aren't authorised retailers which are listed on the website. I just saw that Healthy 18 sells a lot of 3M stuff on Amazon apart from masks. So based my decision keeping that in mind as well. Nothing beats buying from the authorised seller/distributor but not everyone has that option these days, so have to take a calculated risk.
