Also ,for those who don't like to order on-line.
If you live near Micheal's , you can get Oil Based clay , sulfur free , near the Sculpey III , and FIMO.
It says on it from top to bottom :
MODELING CLAY
Plastalina
Van Aken
At 3.80 a pound , it's only a bit more that online and you save on shipping.
Happy Hunting!
