Blue
Ohto is one of the 713 brands in Inktend's built-in ink catalog.
Paper & pairing
Blues and navies are the most broadly "safe" fountain pen colors: legible, professional, and unlikely to raise eyebrows in an office. This ink will behave predictably on most fountain-pen-friendly paper. Cheap, highly absorbent paper (standard copier paper) will dull any ink's saturation and can cause feathering or bleed-through with wetter nibs.
About Ohto
Ohto is a Japanese writing instrument manufacturer established in 1919 as the ink and dye maker Nakata-Ohka-do, which released the first Japanese-made ballpoint pen in 1949. It pioneered water-based ballpoint ink in the 1960s, effectively creating the rollerball category, and today makes fountain pens, rollerballs and mechanical pencils, taking the name Ohto in 1974.
Storing and using the bottle
Bottled fountain pen ink has an effectively long shelf life when kept capped and out of direct sunlight: most inks remain usable for years. The main risk isn't the ink spoiling, it's a pen sitting inked and unused for weeks: that's what causes clogs, not the ink's age.
