abcOralCare, New Generation US Patented, Non Nylon, Tapered, Soft and Ultra fine bristles - Hannull 4 toothbrush - Deep penetration pack of 4
These toothbrushes are made with US patented technology that make tapered ultra fine tip bristles, 0.01mm-0.03mm, for deep cleaning. Bristles are extremely gentle. Long and flexible action tip bristles are specially designed to help clean the innermost area that is hard to reach in the mouth. The horizontal-pattern of the bristles provide an intensive cleaning activity. The oblique pattern of the bristles help clean interdentally. Also the triangle pattern of the bristles help clean the indented surface of the teeth. Ergonomically designed handle with non-slip surfaces offers a flexible and slender neck to better control the recommended brushing pressure.*** DuPont developed nylon bristle in 1950s, and it has been used in most of the toothbrushes. Toray developed the new generation P.B.T. tapered bristle in 1972, and it has mainly been used in Japan & Korea.*** The new generation toothbrush has been unavailable in the U.S. market in massive numbers due to the patent protection until abcOralCare, Inc. produced and distributed it in the U.S. market.***Our business is to make and sell the highest quality oral care products at the most competitive prices possible.
