Is the nylon hair of hotel dental appliances better or the sharpened hair?

Of course, sharpening is ok, but the cost of sharpening is higher, but sharpening sells better. If you use the antibacterial toothbrush filament of Shenzhen Wang Xiong Boutique Toothbrush Co., Ltd., it will sell better. I heard that they specialize in making bristles. They have cosmetic brushes, nail brushes, toothbrushes, brushes and other raw materials, and they have environmental protection test reports, so it is no problem to export them to Europe and America.
