According to price quite good . Here I include one picture how they look like on watercolour paper but once they dry colour feels matte, lifeless . Colour feels chalky. Colour faded almost immidiately if you are using light layer of colour. They don't pop up while layering them . For using this colour you have to apply first layer thick because once they dry they will fade immidiately , good for one stroke painting ,calligraphy bad for portrait or detail relaistic painting.
They took a hell lot of time to dry . So you will be impatient while painting and it is difficult to get dark colour even from black colour itself.
For getting dark colour apply first layer thick then wait to dry then apply another coating. Repeat this process untill you are happy. It will take a hell lot of time to get dark colour but with patient you could achieve good result. And they are better than tube camlin artist paint .
Box feels cheap and colours are hard as rocks but wetting them is not a difficult job.
For a long time I was quite fustrated with the product
But as I mensioned not bad watercolour according to price
