I hope this email finds you well. I’m writing to recheck about you already sent sample back because I get notify form Customs Department about I have the sample from India belated over there.
I would like to make sure that this shipment sent from you. If, you sent, please inform me about name and address that you declare.
Furthermore, I have attached invoice that I got form Customs Department within this email to inform you.
However, if you didn’t send it back please kindly notify me before ship the samples back and declare the shipment as sample with no commercial value, price at $1.
