Marlin, an American customer, is a very big customer of ours. We have cooperated with each other for 11 years. We got to know each other at exhibitions. We actively make samples with high speed and good quality. We also have staff who are specially responsible for product design, so Mary is satisfied with the samples we make every time. From the initial order of more than 100 sets to the current order of more than 10,000 sets, we always insist on sending pictures and videos to customers for confirmation before mass production. The finished products will also be randomly checked by quality inspectors according to the ISO9001 standard to ensure the quality of our products. Our company has been deeply engaged in this industry for nearly 20 years, so we are familiar with similar products in the market. We often develop new products by ourselves to share with customers. We also hope that our products can be welcomed and accepted by the market.
