The semi-flexible brush tip of the POSCA Brush Marker PC-5BR is ideal for all sorts of artwork where you need tighter control than a fully flexible brush provides, but with more expressive strokes than a bullet or chisel tip gives you. Great for calligraphy and expressive art, can draw lines from 1mm to 4mm as you vary the pressure. Assorted set of 8 Uni POSCA water-based pigment ink brush markers. Writes on virtually any surface with no bleed through on paper. Set contains one each of white, yellow, pink, red, blue, violet, green and black. As with the rest of the POSCA range the Brush Marker Pen works on most surfaces and is permanent on absorbent media such as paper and card, and can be removed from shiny surfaces with a scraper.
