You just received a shipping container full of 10,000 custom backpacks, only to discover the zippers snap on the first pull and the PU leather is already peeling off the straps. At this point, you have already paid the 70% balance, and the supplier is blaming your “design specifications.” Sourcing bags and luggage from overseas is a high-stakes game.

To filter out the pretenders, you must conduct a strict corporate verification process.
