Update: I was really unfair. After playing with the art noise I have found it pretty decent for the price point. The titanium white is opaque enough to get some good mixes.
I do still find the colours a bit dull from lower pigment but for the price it's fair. I did still notice there is a little sheen with a couple colours. Mixing colours is okay, not great. Wonderful in my sketchbook though so I would totally buy them again for this purpose. .....,......................................................................................................Unfortunately I came away disappointed. Very thin and streaky. Not at all opaque for gouache. When dry seems to have a hit of gloss, not fully matte like gouache. I'm sorry to say it is truly craft store quality.
