Good morning, everyone. I've created some offers for amazon.com from my stores in the EU, and when trying to ship to the FBA inventories, an error code appears indicating that no warehouse is enabled to receive my items. By changing my required preparation from 'no preparation' to 'poly bag', the items can be received. Now, if I were to send my items without the poly bag but with their original packaging (a plastic envelope but not transparent as required), what could happen?

Thanks in advance
