As with normal toothbrushes, the brush must be changed regularly because they wear out at some point and it is sometimes even necessary for hygienic reasons.
Are included, as besschrieben, 4 brush and a corresponding number of colored rings to mark the individual. This makes it easy, even within the family to keep track of who owns what brush head.
Packaging and contents were flawless. You have to lose a great word about it.
Because the price is great, there is nothing left to distribute the full 5 stars.
