How to check whether Sandisk Cruzer Blade Flash Drive is original or not

Dear sir

please let me know how can i check that whether Sandisk Flash drive is original or not.

You could ask the store where you bought it.

Hi. I think he bought it from someone else. Checking this would be difficult since there are no serial numbers on flash drives nowadays.
