Vince from Canada sent us an inquiry through Alibaba that the general instrument cleaning brushes that they had purchased from another supplier was easy to bend and deform. He hoped to find a tight and strong general instrument cleaning brushes and hoped that we would give him samples to let him determine the quality of the product.

After receiving the inquiry from Vince, we learned that their previous general instrument cleaning brushes diameter is 20mm, but the single stainless-steel material is 1.0mm. The stainless steel is too thin and the diameter is so large that the stainless steel is easy to bend and deform. Based on his previous size, we recommended that a single stainless steel 1.0mm be replaced with a single stainless steel 1.2mm, and several samples were produced according to the size given by Vince.

A few days later, Vince received the sample of the general instrument cleaning brushes we sent and tested it. He gave us feedback: "The stainless steel you recommended is 1.2mm stronger than 1.0mm. We like it very much, but we want it to be strong. One point, can you make the stainless steel 1.4mm?” After several days of communication, Vince finally decided to place a single stainless steel 1.4mm general instrument cleaning brushes of 3000 pieces.
