10 artists' watercolour markers with an additional colourless blender. 

Highly pigmented water-based ink markers with a nib at both ends. One is a smooth and flexible brush for artistic brushstrokes, the other a bullet nib for high precision, detailed work. Whichever nib you're using, the colours won't bleed through the paper like felt pens sometimes do. The pens have excellent water solubility when used on watercolour paper, and also have high lighfastness. 

The colourless blender is highly suited for blending pigmented watecolour inks.
