Thank you for this review, it sealed my decision to buy individual colours instead of these packages. Individual colours will be much more useful for me even though I admit that the online videos people have posted of these mixes make me drool. I do understand that there are many factors affecting granulation,e.g. maybe pigments in these mixes are more coarsely ground than those in individual colours, and therefore they may behave differently. anyhow, I shall use these ready made mixes more like an inspiration.
