We would like to apologize again for the scratch problems in last shipment. About the scratch drawers, we are willing to send 100% top cover for your replacement as we promised in last email. As we learn from the details of problem in MK-420 & MK-460 you offered as attached, there are total 15 units MK-420 and 19 units MK-460 with scratch, Thus we will supply 15pcs new MK-420 top covers and 19pcs new MK-460 top covers for your complete replacement. Considering the top covers are hollow and will probably get damaged if they are sent alone, we hope to send them with your next order, which we think will be a good way. Hope your could understand and your cooperation is genuinely appreciated.
