These Friendgo Markers with doublie line pen are awesome to outline, because they already create a beautiful outline. The price is incredible cheap, only 1,40 per marker and the package comes with eight different colors.
The main problem, is that it won’t work well in papers that are below 80gsm, strike through will happen.
