In March, I received an email from John customers in the United States that the beaker bottle brush that was ordered from another supplier was not clean, and asked Aoqun to help it solve the problem of unclean beaker bottle brush.

Our sales customer service Mary responded promptly 1 minute after receiving the customer's email, learned the size of the beaker bottle brush that needs to be ordered, and found that the density of the brush ordered before was very sparse. In order to control costs, the original supplier reduced the amount of brush filaemnt, and the test tube was not clean. Mary suggested that John thicken it by at least 20% on the basis of the original density, and took a beaker bottle brush with a density similar to the picture and a dense cleaning effect video comparison chart to John.

Two days later, John received a sample of the beaker bottle brush and tested it for the first time, and found that the samples provided by Aoqun were very clean. He gave us 30,000 orders that day.
