It’s definitely a value for money product. It colors beautifully if used as a sketch pen. Color is opaque and dark color can be easily used over light color without smudging (ofcourse paper quality matters). For calligraphy/lettering I will say that it’s bit tricky to use till u get a hang of it. Good news is they have two black pens which actually helps you to practice bcoz as a beginners one can easily run out of black after practicing. Attaching my two arts, one for calligraphy and other for simple coloring. Hope it helps. Happy coloring.
