two flexible points for deep and smooth oral hygiene. Effective yet gentle at the same time. This toothbrush is equipped with two flexible points that make oral hygiene more effective and at the same time easier. The first flexible site is located right between the brush head and the beginning of the handle and is like a semi-rigid plastic una ball which, when we try to move it with our fingers, we think "wowthisissoharditdoesn'tmoveatall" but then, in fact, when we go to brush our teeth, we realize that it gently follows the shape of the dental arch and does its job very well. The second movable point can be easily seen with the naked eye as it appears as a small zigzag area una located about 1/3 of the way down the toothbrush.
