Some time ago, Mr. Jorge from Colombia found us through our official website. He said that they are a large buyer and need to purchase 5,000 sets of soft narrow instrument cleaning brushes. He said that they had previously purchased a number of brushes from other merchants, but the bristle was very hard to scrape the customer's plastic tube, so they wanted us to recommend a soft narrow instrument cleaning brushes for him.

From the mail sent by Mr. Jorge, we found the ID of Jorge’s social media, we talked to Mr. Jorge through WhatsApp and learned about the specifications of the narrow instrument cleaning brushes he had purchased before. It was too large, so we chose a soft brush with a wire diameter of only 0.1mm. Then we sent a narrow instrument cleaning brushes sample to Jorge with similarly size.

Jorge received it and compared it to the previous narrow instrument cleaning brushes. He was very satisfied with the soft brushes we recommended because our brushes are particularly soft. Jorge placed the order to us and paid in the same day.
