Paper & pairing
Warm tones (oranges, yellows, ambers) show strong contrast between light and dark areas of each stroke, which is part of why they're popular with broader nibs. 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 Ink Mazeru
Ink Mazeru (from the Japanese word "mazeru," to mix) is a blendable fountain pen ink line from KA-KU, a Japanese pen retailer based in Osaka. The water-based dye inks come in numbered, emotion-themed base colors formulated to be mixed freely while keeping good color development and low cloudiness, and the line also includes shop-original colors created for individual stationery stores.
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.
