The 4Artist Marker pen is a multi-technique oil-based paint marker. The range of colours offer a glossy, highly pigmented finish with excellent lightfastness throughout. They can be mixed together and worked with a brush when applied to a non-absorbent surface. There are 4 different thicknesses of nib (from 2mm up to 15mm) which allows for versatility when creating artwork with them. They are ideal for applying on smooth and non-porous surfaces and are quick drying (5 to 15 minutes depending on the surface and thickness of application) Similar to oil paint, the colours can be diluted and reworked with odourless mineral spirit to obtain differing shades, gradients and tones on most surfaces. They can be applied to most surfaces including canvas, paper, plastic, wood and metal. Ideal for drawing, outlining, filling in large areas, glazing and mixed media. For special effects, simply saturate the tip with colour to create splashing and dripping effects. Uniform in application, there is no colour variation from wet-to-dry. They have a black aluminium body and a coloured cap, making them easily identifiable.

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.
