Unfortunately, the colors go very hard on the children's hands (and also my ex). Even after treatment in the bath with nail brush, washcloth and scrub extreme that children indeed particularly like, the color is indeed from the skin becomes discolored even longer, especially red and blue. Therefore, this color is not suitable for me. Although it has been well tested by Ökotest I have no desire, after painting a complete bathroom to organize. One would like him some day just like that between painting times and then wash your hands and you're done. That is impossible in my opinion with these Farbein Too bad !!
