INTRODUCING ERGO PRO BY DERIVAN 
Derivan has created the Ergo Pro Brush Illustration Markers.
As the name suggests these markers are perfectly balanced for ease of use. The tips are firm and allow the ink to flow at an even rate, which is important when covering large areas with colour or creating shading effects. 
DUAL TIPPED 
Each marker has a chisel and a flexible brush-like tip. The chisel tip is firm and perfect for covering large areas with colour, while the brush-like tip is best for outlines and intricate and precise details where a softer stroke is required. 
The inks used in Ergo Pro Markers are also smooth and even, so the colour you get at the first use continues throughout the life of the pen. They are also fade resistant, waterproof and acid free when dry.
