Better than a bath mat

I hate bath mat: it is aging badly and it's ugly. I stuck fifty pellets that are approximately 4 cm in diameter in the bottom of my bathtub and really, there is no picture: it's quiet, it does not come off (strong adhesive, please confirm with the time) and it's nice as hell. There is still some thirty tablets, if ever it were to take off later ... Frankly, it looks to me to be solid. Anyway, my son no longer bring her bath mat to sit the baby in the bathtub !!!
