dhgate.com - question on authenticity

alright I am thinking about buying these sandisk memory cards through dhgate.com. The seller has good feedback and everything, but is it possible to make a copy of a MEMORY CARD? I mean even if it is and the one i want to buy is, would US customs have any idea if it was a copy/fake? If someone could please help me that would be great. THanks.

im not an expert on those things but i dont think there would be amy way to tell! Even if it was a memory card is a memory card. Hope i helped you out a little!

yeah except the guy that had em on dhgate.com took them off:-(
