I recently got an adult colouring book as a gift, what a great stress reliever it is. But I got colour pencil with it. Me being a perfectionist I like Rich colour and the pencils were not doing it justice so I looked online for some art markers and these were recommended. Now I tried to choose between the chisel and the brush tip and ended up choosing the chisel because they were cheaper and everyone I asked said it was personal preference. I'm glad I did choose the chisel, the tip has multiple angles that you can use for colouring. I love these markers.
