> - sometime, the same product, between two batches, is not produce by the same sub-contractor Case example: I have two pairs of a specific model of cycling gloves, both are subtly different in materials and have different labeling styles, as well as different "made in" statements (one European, one Asian). Had I bought them from Amazon I might wonder which one is fake and it wouldn't be clear at all. But I got both pairs directly from company HQ stocks, the closest thing to a definition of "authentic" we have in today's inscrutable networks of subcontracting.
