Thank you for your prompt response. I appreciate your effort in providing a better offer. I have a couple of questions for you:1. May you please send me some more HD pictures of your KF94 mask? 2. Is the mask packed individually or in bulk? If you may also send me pictures of the packing?3. Does the mask have any certification? such as FDA or CE?4. Before proceeding with the PO, is it possible to send some samples at cost and I will pay for transportation?
