I don’t see this item listed on the official Sandisk website.
Could this be a fake? Just to be safe, I bought the “older” 60MB/s version, but if this turns out to be a fake, I would even question the authenticity of the one that I have.
if the card was sold by amazon directly then the card is genuine and you can use it normally. In order to be 100% sure you can also contact the sandisk support to ask them if this card exists.
