If anyone's interested I found a great source for modeling powders. These are the rub on self adhesive type. The company is Bragdon Enterprises out of Georgetown, CA. Website is bragdonent.com . Check them out as they have a lot of other items for molding as well. The nice thing is the containers are huge, about 1"x1"x3" with a lot of powder and a set of four is only $22.00 plus shipping. Compared to other brands this is a huge amount of powder for the price. I just paid $35 bucks for 5 small Mig contains with maybe a third of the powder in them. Anyway hope it helps!!!!
