Hey Likwacheng, this looks legit - our playing cards are printed on the same machines at the United States Playing Card Company that manufacture Bicycle, Bee, and Tally-Ho cards, and border thickness - particularly of a very thin-bordered deck - can very slightly. Usually, border thickness is more uniform than this, so I'll absolutely pass this example along to USPC to aid in continued improvement of border thickness precision. But yep - these look legit.
