Yes , the price of our masks is higher than the price of Nanjing , but we can guarantee the quality,we chose the expensive material to make them and the workmanship is very meticulous. The inner shell of our mask is make of copper , they can't rust . So, the cost is high .You can buy a mask from Nanjing and compared with us ,then ,I believe you will understand it.
We real want to cooperration with your friend , but the price ,we can't reduce them ,hope you understan us .
Thank you !
