In April, after receiving email feedback from Brian in the United States, the instrument cleaning brushes ordered before scratched the inner wall of instrument, causing a large number of customer returns, and the order quantity is continuously decreasing. Is there any way to prevent scratching?

Our sales customer, Mary, responded promptly after receiving the customer's mail for 1 minute. Brian sent a picture of the instrument cleaning brushes and provided the size. In order to save costs, the former supplier used the cutting process for the head, and it is easy to scratch the inner wall. Mary suggested that the brush head should be dispensed, because the head will be smoother after dispensing. Brian was very interested in Mary's suggestion, asking us to send 3 sets of instrument cleaning brushes samples for testing. We sent samples on the same day.

Two days later, Brian received the instrument cleaning brushes and tested it on the same day. It was found that the provocative brush did prevent the inner wall from being scratching. After 3 days, Brian gave us order of 60,000 pieces.
