I hope that you are well. I would like to request a supply quote for the above item in 50ml size. If your supply quote is good, we are looking at 5,000 units or more for the first initial order. Of course we will first need to do a sample test order. I would like to know the available quantities, manufacture date and Country of Origin for calculating duties in South Korea. Thank you and I will look forward to your correspondence. Best regards,Stephen Kim
