Sakura Koi Color Brush Pen (Viridian)

Sakura Koi Colour Brush Pens perform similarly to an artists' brush - they can produce fine, medium or bold brush strokes just by changing to amount of pressure to the nib.The nib is made from a durable, flexible nylon and so will quickly spring back to its original shape. It has an odourless water-based solvent which means you can blend and layer colours smoothly, creating a range of hues and effects. The colourless blender pen can be used to create seamless washes and colour gradations.pdf=koicoloringbrush-colorchart.pdf Koi Colour Brush - Colour Chart.
