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 serve as excellent cleaners for braces. This is a practical starter set with 5 CPS 07 size interdental brushes that can be attached. The brush is red, has a 2.5 mm effectiveness, and a 0.7 mm flexibility. Also included are two different red holders. The CPS prime 07 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.
