Mr. Jiang from Zhejiang said that he recently received complaints from customers that the glassware cleaning brush glasses didn’t have a good cleaning performance and scratched the glassware, result in the cargo returned and he lost a lot of money.

Mr. Jiang sent the drawings of the glassware to us. We immediately discussed and offer 4 solutions. Finally, we made four bottle cleaning brush glasses with different head process according to Mr. Jiang's drawings. After testing for many times, we found that the bottle cleaning brush glasses with twined coil process had excellent cleaning performance and not scratched the glassware. Finally, we sent this bottle cleaning brush glasses sample to Mr. Jiang.

After 7 days, we received a call from Mr. Jiang：The bottle cleaning brush glasses samples we sent were excellent and the market feedback was very good. He didn’t receive a customer complaint any more. Mr. Jiang eventually purchased 8,0000 units from us.
