Red
A Japanese brand whose Classic ink line is designed to resist clogging, pairing naturally with Platinum's slip-and-seal pens.
Paper & pairing
Reds and pinks show the most dramatic shading of any color family — expect real variation between the edges and center of each letter. 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 Platinum
Founded in Tokyo in 1919, Platinum is one of Japan's "big three" pen makers, best known for the slip-and-seal cap technology that keeps a pen from drying out for months.
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.
