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 GuangBo
GuangBo (Guangbo Group) is a large Chinese stationery manufacturer founded in 1992 and headquartered in Ningbo, Zhejiang. It became China's first listed stationery enterprise and produces paper products, notebooks, and office supplies, with other business lines spanning new materials and cross-border trade.
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.
