Waterman Paris Fountain Pen Cartridge Serenity Blue 8 Cartridges 2 Pack Large Size Standard Refills for Waterman Pens Smooth Flowing Inks for Luxury Writing

They're Waterman cartridges for Waterman fountain pens. The fit, they don't leak and they are the right color.

I love them! They are easy to put in my pens, and they last for a long time. They don’t bleed any more than other ink I’ve gotten in the past. I’ll definitely be getting these again when they run out. Highly recommend!

Waterman makes perfect ink for their pens. Almost a must for Watermen pens.

These cartridges glide smoothly and flow effortlessly. They’re the best value for money, and they fit perfectly! They don’t leak when you’re writing or when you’re storing them, and they seem to last a long time. They’re sturdy enough to carry a spare in your pocket or glovebox, so you’re always covered. I picked up the blue cartridges, and the color is just right. It’s bright and vibrant.

I only use fountain pens to write, only use blue ink, and I have a preference for Watermen. I love the refills because the ink flows out nicely. It doesn’t blob, bleed, seep through. The biggest love is that it doesn’t stop flowing when writing, so I don’t have to go back and trace over what I’ve just written! I highly recommend this for all levels of fountain pen users.
