Professional teeth cleaning made easy: thanks to the practical and easy-to-use interdental brushes from Curaprox. These interdental brushes gently and effectively clean all interdental spaces - available in five sizes and five colors. They also work very well as braces cleaners. This is a practical starter set with 5 pieces of interdental brushes in size CPS 09 for attachment. The brush is yellow, has a 4 mm effectiveness, and a 0.9 mm diameter. Also included are two different yellow holders. The CPS prime 09 is the second smallest of the five prime brushes. The new replacement head easily clicks onto the existing holder. The refill pack is environmentally friendly and reduces waste. The CPS prime brushes were developed and manufactured in Switzerland.
