Madisi is not a well known company. I have only found these four sets of paints. The price for them is pretty decent, so its ideal for artists who are starting to paint. You get the best for your buck. The product is non-toxic. This is important since little kids for some reason like to eat paint. I do not know if the paint is edible. Frankly, I would prefer if people did not eat paint. Madisi is also sun resistant. This is good if you want to put your artwork near the sunlight. Paints usually gets withered away by just about anything. Just look at what became of the Last Supper.
