Yay-Yay!!! I have tested the @sketchmarkersclub markers.
I like them.
I didn't draw with markers in basic complectation, I bought markers with brush nib immediately, so I can't compare them. But I can compare it with copic, which are much more expensive. And I didn't notice much difference. The nib is cool, thin and elastic, does not concede to to copics.
This portrait was drawn only by #sketchmarkersclub.
I plan to draw one more art using copics too, and then I will compare markers in more detail.
