Platinum Ink Cartridges 10 Pack – Blue/Black
The Platinum Ink Cartridges 10 Pack – Blue/Black is a treasure trove of ink to fuel your creative endeavours. Each pack contains ten SPSQ-400 ink cartridges, meticulously crafted to fit seamlessly into all Platinum fountain pens, including the beloved Preppy model. With this generous supply of ink at your disposal, you can write, sketch, and express yourself freely without worrying about running out of ink. *Note on colour: Platinum's 'Blue-Black' is actually a pretty standard mid-blue colour, rather than the very dark blue more commonly associated with this word. Because it is an iron gall based ink, caution should be given when using it in fountain pens that do not have gold nibs. This ink has the added benefit of being permanent, and it will eventually turn black instead of blue. 6 mm outer diameter 4.1 mm inner diameter Made in Japan
