Marvy's Le Pen Technical Drawing Pen has pigmented black ink that resists bleed-through and is permanent when dry.
Perfect for manga, anime, and anything else that requires black outlining or brush strokes.
Tip sizes range from an extremely fine 0.03 mm to a medium 0.8 mm and even a brush!
LEFTY TEST: A+ on the super fine tips but the broader ones more like a B.
The "Lefty Test" is a grueling process of writing with a particular instrument and then immediately attempting to smudge it. Lefty Tests are conducted on pages from the Shorthand Standard Notebook. Other paper qualities may yield varying smudge results.
A+ NO smudge
B A slight smudge; maybe needs a second more to dry
C Significant smudge
F Hard fail
