Paper & pairing
Purples sit at the boundary of professional and playful, one of the more personality-forward choices that still reads clearly on the page. 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 Blackstone
Blackstone is the house pen and ink brand of JustWrite Pen Co, an Australian online pen retailer established in 2000 and based in Blackstone, Queensland, from which the brand takes its name. Its Australian-made fountain pen inks include the Colours of Australia and Scents of Australia series, with names like Sydney Harbour Blue and Uluru Red, plus the waterproof Barrister line.
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.
