The perfect accessory to Staedtler's pigment art pens this ink blending liquid really does it all. 

The liquid can be used for mixing of colours, creating smooth colour transitions and gradients, creating watercolour and ombre effects and even for brightening colours, creating light reflections and correcting minor errors. 

For application of the blending liquid you can simply apply the liquid with a brush or pour the liquid into the tank of a water brush. It can then be swept over the surface to be blended until the desired effect is achieved. Can be used even when the ink has dried.
