SUMI 1 to 4 - the multipurpose ones. Based on the TRUE PIGMENT BLACK black pattern, the constant shades of gray are suitable for both fillings and linings and also have all the advantages of big brother. Thanks to the well-thought-out proportion of the gradations, they form a clear and sensitive portfolio of high-quality grayscales, making it superfluous to laboriously reconstruct the shades for your own vegan and acrylate-free mixes.
