I love that this set is all in one. The paint cakes are on the tray and so is water wells. There are also spots where I can mix colors. The paint cakes are large enough to create many paintings. They aren't messy like liquid paints can be. The colors are bold and bright. When I am done painting, I just put the top on and let the cakes dry out for storage. When I want to paint again, I just add water and I am ready to go.
