Thank you for your feedback. However, we'd like to have pre-production samples as well for the production of first order. This is the process we have informed at the beginning. If you prepare this sample to correct the error point. We will waive for pre-production samples. This is to avoid any problem on production and our shipment. I do hope you understand. Thank you in advance for your cooperation.
