How Much Ink Does a Parker Cartridge Hold?

When it comes to the beloved Parker pen, one might wonder just how much ink is packed into those sleek little cartridges. The answer is quite impressive. A standard Parker cartridge can hold up to 1.4ml of ink, which is quite a generous amount for such a small device. However, it’s important to note that these cartridges aren’t filled to the brim.

Within that 1.18ml of ink, there’s also a reserve of 0.15ml, known as the emergency reservoir. This additional ink serves as a backup for those moments when you find yourself in desperate need of a refill but cant find a spare cartridge. It’s a clever feature that ensures you can keep writing for a little while longer, even when you thought you’d reached the end.
