My answer to your question was not totally correct (when you asked me about the procedure for the samples to ABC customer last Friday.) I was confused about the steps with BCD customer. I would like to revise it for you again:
For my pervious arrangement / handled, (I don't know what this means. Do you mean "As per my previous arrangements for handling, I will . . . . "
I will inform the factory to prepare the specific samples and I will arrange delivery of the samples to the customer's office.
directly after the mass production is no problem. (I don't know what you mean here)
The customer will review the sample and send 2 pcs to their US office themselves. Finally, I will return the receipt to our marketing department for their reference.
