A single blue ballpoint ink refill for the Platignum Studio pen.
Platignum Pen Co., London, introduced the world's first self-filling fountain pen in 1919. Throughout the last century they have engineered a unique line of writing instruments, inventing the first replacement nib, retractable ballpoint and replaceable ink cartridge. The modern Platignum Company continues in that tradition, creating well-made yet affordable pens designed with thoughtful details: smudge-proof and hybrid inks, soft grip barrels, and attractive, sustainable packaging.
