UNI POSCA - BLACK marker Bold- (8mm)
UNI POSCA - BLACK marker Bold- (8mm)
The Uni POSCA PC-8K is one of the most versatile broad markers ever produced—equally capable of clean calligraphy, bold graffiti fills, sign work, illustration, and layered mixed media applications. Built around a durable 8mm chisel tip and loaded with highly opaque water-based pigment ink, it delivers dense black coverage with smooth control across nearly any surface.
Unlike alcohol-based markers, POSCA ink will not aggressively bleed through paper, making it especially useful for sketchbooks, practice sheets, posters, and layered design work. Once dry, the pigment becomes water-resistant and highly durable while maintaining a matte, deeply saturated finish.
Balanced between precision and coverage, the PC-8K has become a staple tool for artists, writers, designers, and sign painters worldwide.
