Jimmy from France sent us an email through the official website. He said that we saw our official website and were very interested in our instrument brush cleaning set. He hopes that our instrument brush cleaning set is soft and not too hard. Because the instrument brush cleaning set he had purchased was too hard, the inner wall of the medical instrument was scratched, and even some of the medical instrument was broken.

We analyzed to Jimmy that the larger the filament diameter, the harder the wool, and the material will affect the softness and hardness of the wool. Nylon is the softest, but it does not rule out the use of PP filaments instead of nylon filaments. For the instrument brush cleaning set, the wool yarn we generally use is a nylon 0.1mm-0.2mm filament, and the wool in this range is very soft, so there is no need to worry about scratching the inner wall of the container. We even sent our existing instrument brush cleaning set to Jimmy for reference.

After receiving the sample, Jimmy gave us feedback: "Your instrument brush cleaning set is really soft, much softer than the instrument brush cleaning set I purchased before. I tried to clean it, the effect is still very good, I am very satisfied with your product, let Let's talk about payment." After several days of negotiations, we finally reached a cooperation.
