Blue
Delta 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 Delta
Delta was founded in 1982 near Naples by Nino Marino, Ciro Matrone and Mario Muscente, and built its reputation on bold Italian designs and materials, most famously the orange resin Dolcevita line. The company closed in 2017, and several of its former staff went on to found Leonardo Officina Italiana and Maiora. The brand was re-established in 2022 under Maiora with co-founder Nino Marino leading production in southern Italy, offering resin and celluloid pens with steel or gold nibs in the several-hundred-dollar range and above.
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.
