My first painting was a simple sketch of an apple. As with any other watercolour paint I decided to let the paint do the work. The pigments were quite strong so I expected the task to take only a few minutes. Unfortunately the paint didn't behave as expected. The paint didn't adhere to the paper very well and was difficult to layer. Each subsequent layer seemed to lift of the previous layer. Also, the stronger pigments seemed to bleed and dissolve the dry paint underneath leaving large watermarks. It took an awful lot of work with the brush to correct the problem.
They are loaded with pigment with some unusual colours. Not really a beginner's tool as they are quite difficult to work. It might be best to try them on a variety of different papers to get a better perspective of their potential. Worth a try but if I were to start from scratch I would go for one of the student brands such as Van Gogh or Cotman. On a positive note, they are inexpensive for what they are.
Foot note: These paints that I purchased were unused but I guess quite old. I wonder if the problems that I had might have been down to this product having a limited shelf life.
