Renesans drawing ink EXTRA INK is made to a very traditional recipe. One of the basic ingredients is shellac, which ensures a delicate gloss, fastness and depth of black shade. The ink is water resistant after drying and its black is very intense. Can be thinned with water if necessary. It’s a result of using a maximum concentration of highly lightfast black pigment. It works very well with a brush or with a proper nib. Available in 30 ml plastic bottles and in 100 ml, 250 ml, 500 ml and 1 litre bottles.
