Iroshizuku ink, take-sumi, is one of my favorites - this bottle is black ink - but there are 23 other colors to please. Do you not love the bottle!? The fountain pen is another favorite of mine. This pen is black gloss with a 18K gold nib. This pen is retractable making it one of a very few in the fountain pen world and I do believe this Pilot brand is the only one that is effecient and trouble-free. Uses cartridge or draw up some of the beautiful inks available at pickle papers - including the Iroshizuku Japanese ink.
