Some time ago, I received an inquiry from American customer Mike that he wanted to buy a test tube brush 16mm. Mike said that he bought a test tube brush 16mm from a Zhejiang manufacturer in China previously. After using it, he found that the filament was rough and hard, and the test tube would be scratched. He received many customer complaints and seriously affected sales. So, this time Mike purchased a test tube brush 16mm and decided to change the supplier and asked if we could solve this problem.

Our gold customer Roger told Mike, "Aoqun ’s pure nylon is flexible, bright in color, and the diameter of the filament is ± 0.2mm. And our product manager has a customized solution within 8 hours. It is certainly possible to customize a test tube brush 16mm for him. Problem. After we received the product drawing from Mike, considering the filament rough and hard scratched that Mike encountered before, we chose black nylon with a diameter of 0.15mm for it. Mike was very satisfied after hearing it, A few days later, we successfully completed the test tube brush 16mm sample and sent it to Mike.

Two weeks later, we asked how well the Mike test tube brush 16mm was used. Mike was very pleased to tell us that the test tube will not be scratched after repeated use, and the quality is very good. He has also received many customer orders.
