Sailor Jentle Bottled Ink is filled with 50 ml of a water-based dye ink that is designed to be used with all fountain pens. The internal reservoir of the bottle allows you to use all of the ink in the bottle without any waste. The high-quality ink is smooth-flowing and the unique bottle allows you to easily fill your fountain pen. There are a variety of colors available.
Sailor Jentle black in the 50mL bottle is great. The little insert/ink-well is nice. There have been complaints that it's too shallow for some pens, but I actually fill my converte... view morer directly, and then put the converter into the pen. (Ink's surface tension keeps it from falling out of the converter.) I love this bottle so much that I'm going to hold onto it and fill it with other inks when I use all this up. view less
