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 Sulekha
Sulekha is a historic Indian ink maker born of the swadeshi self-reliance movement: chemist Satish Das Gupta, at Gandhi's urging, handed his ink formula to the freedom-fighter Maitra brothers, who began production in 1932 and moved the works to Calcutta in 1936. After suspending operations in the late 1980s, the Kolkata company revived and relaunched its swadeshi fountain pen ink line in 2020.
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.
