Max from the United States said the diameter ofnarrow instrument cleaning brushesfrom other suppliers before is too large. The large narrow instrument cleaning brush didn’t fit to clean the small tube. He asked us if we can produce a narrow instrument cleaning brush that to be able to clean the small tube.

Our customer service responded after receiving the mail of Max in 1 minute, the small tube has a diameter of only 1mm but narrow instrument cleaning brush that purchased from other supplier has a diameter of 3mm, which will not have a good cleaning effect. We recommend Max to use a narrow instrument cleaning brushes with a diameter of 1mm. Max was very happy to hear our advice and was also a bit worried, so he asked us to provide 10 samples for his test. We sent 10 samples with 5 days.

3 days after, Max received samples and arranged the test in the first time. The size of the narrow instrument cleaning brushes is very suitable to the small tube. It will not be too large to insert into the small tube, also not too small to have a bad cleaning performance. Max placed us an order of 3,000 sets and said that if he sells well, he will introduce other customers to us.
