Platinum Pigment Blue Ink Cartridges only works with Platinum pens.
Pigment ink has much higher lightfastness and water resistance than dye-based ink, ensuring that your writing lasts longer.
Platinum Pigment ink is resistant to water and is feather resistant, which results in sharper lines ideal for writing that requires detailed lines.
Once it dries, even if it gets wet in water, it prevents the colour from spreading and vanishing.
It's recommended to clean the pen once a month if using the pigment ink as it can clog if left to dry in a pen.
Package consists of 10 Blue ink cartridges.
