The Nimbus® Microfine® has two states of soft bristles: long-tapered extra fine bristles to reach into those critical areas with the required softness and effectiveness – coupled with shorter, fine support bristles to enhance optimum plaque removal. Microfine® toothbrushes use a multi-tufted, soft bristle technology mounted on a comfort-engineered handle. Long tapered and short end rounded extra-fine, flexible bristles clean the hard to reach places; gently and effectively. The Nimbus Microfine has been tested and evaluated by dental professionals. The result is the best brush you or your patients will ever use. 10 individually wrapped toothbrushes comes in assorted colors, in blue, green, yellow, red and lavender.
