Let me tell you something, these water based brushes are very versatile for sketching ideas, playing with color combos and travel friendly as watercolors. I use them in my professional design field during the idea stage and for my hobby time with personal projects. I know Ohuhu is known for having a cheap alternative of the Copic Alcohol Markers but these water-base markers and their fineliner/brush combo impresses me greatly and motivates me to try any new products.
Kudos Ohuhu! Looking forward to your biggest set of your brush alcohol markers.
