HI I ordered 3M 8210 Plus masks from JUMIA Egypt. I received the masks and I was supersized that they looked different from the original I know. So I check 3M website and noticed that the 3M 8210 Plus strap is made of dark yellow tissues, while the masks send to me have a strap made of yellow plastic. Of course the strap is not the issue but this means one thing, it is not manufactured by 3M. The strange thing is that I noticed the (Lot# number) starting with 10 ! which means that it was manufactured in 2010. So it is actually expired masks ! Ironically Jumia refused to return the masks ! Can you help ? I think this is not acceptable. I attached photos. Thanks
