SanDisk Ultra SDXC 64GB class 6 - authentic?

I got an SDXC 64GB class 6 card, however, I cannot seem to find any information at all about this card.

Image search only got me a couple of images of smaller SDHC Ultra cards with class 6 specification.

In another thread, someone wrote that SanDisk recently upgraded their Ultra line to class 6, but I couldn’t find any verification.

I attach an image of my card.

Thank you in advance for your replies!

I contacted support and they told me that this card is a new product that has just been released into the market.
