Faber Castell's Goldfaber Sketch Marker.

This alcohol-based sketch marker features two nibs: a soft flexible brush tip for artistic work and a metal-encased fineliner tip which creates a 0.4mm line for contours and finer details.

Available in a range of colours, the ink is waterproof and smudge-proof. 

Made from 100% recycled material. Barrel colours may show slight variations due to how they are produced.
