For the 100th anniversary of Sakura there are these special editions. Two sets of the high-quality fineliners in black and gold, very art deco due to the contemporaneity of the emergence of this style and the development of this fineliner.
The Pigma Micron Fineliners come, like all pens from the Sakura Pigma series, with a deep black, document-safe pigment ink. This gives your work a long life, because it is quickly smudge-proof, permanent, lightfast, pH-neutral, waterproof, and resistant to certain chemicals. The ink won't bleed through most papers and lines stay sharp on the paper for excellent copying of your work.
Use the fine drawing pencils for manga, to illustrate and sketch - and with the precise, metal-encased tip, it's ideal for technical drawings. With the waterproof ink, you can also use the fineliner for outlines in combination with watercolors or markers.
