How to verify if the Factory Seal is authentic on a Revised booster box?

[A1phaMale]

Are there any tale-tale signs that a "factory-sealed" Revised booster box has been tampered with and re-sealed? I own several boxes and the seam on one of the boxes goes beneath the box on one side whereas the seam goes around the sides for my other boxes. Other than that, the seal around my boxes are basically the same.

Were all boxes sealed in the same fashion? Any other way to verify that the factory seal is legitimate?

Not sure tbh, but I know of one bloke who'd kept 3 boxes, scanned them to get the good stuff out (trivial pre 4th/Ice Age) and repacked 2 boxes, free of sol rings, tutors, fastbonds, wraths etc and rich in lifelaces and ante cards. Sealed at work and sold them on. He even bragged about it after he'd flogged them. Scum.
