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 Arcus Artisan Inks
Arcus Artisan Inks is a Philippine fountain pen ink brand made by Arcus Hobby PH, a maker that began working with pigments and water-based acrylic paints in 2021 before expanding into inks. Drawing on its color-science background from the paint industry, it produces water-based fountain pen inks in 50 ml and 20 ml bottles along with ink mediums and pen cleaners. Products are sold through its web store and Shopee Philippines.
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.
