For us as Vielkneter the best clay. They are available now in many beautiful colors. It smells delicious and is as soft as butter. Even a slightly longer stay in the air, it does not matter. It remains quite a long playable. Like any soft clay of course remains very much like the clothes, sticking with the slippers, under the fingernails, and sometimes in the carpet. After complete drying it can be but rub out quite well.
