I received an email from Ivy saying that she needed to order the filter stem brushes. She reported that the filter stem brushes ordered from other suppliers had rusted, the fish pond ecological environment was damaged, and Causes customer complaints. Ivy asked if we could provide a non-rusting filter stem brush.

Our sales customer service Mary taught Ivy to identify the grade of stainless steel in the email. It was found that Ivy has been using 201 stainless steel, and the use of the filter stem brush is near the sea. Mary told Ivy's filter stem brushes that they usually need to be grade 304, and because of the proximity to the sea, the salt content in the sea is greater. Mary recommends that customers use a higher grade of 316 stainless steel, which is more resistant to rust. Ivy agreed with our analysis and asked us to provide her with three samples of 316 stainless steel filter stem brushes, and paid the sample customization fee. We sent the samples after 3 days.

Four days later, Ivy received a sample of the filter stem brush and took it to the field for a month. He found that the anti-rust effect was very good, and then we placed an order for 10,000.
