360do BRUSH's bristle is super thin as 0.09mm each, which is around HALF compared to those of conventional toothbrushes (0.17mm - 2.0mm).
Each 360do BRUSH's head consists of 13 - 15 bunches of those bristles, and each bunch has 1200 bristles welded to the centre.
Therefore total number of bristles at each head can be counted as 15600 - 18000pcs, whereas conventional toothbrushes have only 700 - 1000 bristles in general.
That means, 360do BRUSH head has about 20 TIMES MORE bristles than conventional one. It leads to give you much softer feeling and much better attachment to the teeth and gum.
