SAKURA Pigma Graphic Set Calligraphy  (Pack of 4, Ink Color - Multicolor)

When artists want dark, bold pen strokes that last, they turn to Pigma® Graphic™ and archival Pigma® ink. The Graphic1 pen nibs are designed to meet the specific needs of illustrators, cartoonists, and manga artists by enabling a broad range of illustration techniques. The 1mm bullet nib is ideal for shading, texturing or filling in large areas. || Sakura Color Products invented and patented Pigma ink in 1982. This special formulation of pigment-based ink molecules is more chemically complex and 100 times larger than dye molecules. This makes Pigma ink less susceptible to UV rays, chemical degradation, and pollution from contact with oils and other chemicals. Pigma ink has become the standard for what is defined as reliable, permanent, archival quality ink.
