4 Pack (20pcs) Picasso Ink Cartridges Fountain Pen Refills (Black)

fits well in the pens and last a very long time. with my use of everyday.

I bought these cartridges to ink a couple of fountain pens that I own. They work very well. The color is dense. The only think I might wish for is that if they were water-proof, but they aren't. But I'm quite satisfied with the product as is for what it is.

Nice packaging. However, it does not seem to fit the Picasso pen for which I bought them (Picasso 606).Perhaps I am not doing it correctly. (I wasn't!)UPDATE: Cartridges do fit. Had to read the item description on the Amazon listing. Would be better to put this with cartridge package.

I was frustrated that the name brand ink I bought from a local office supply dried in the nib of my new Picasso pen so quickly. I bought this Picasso ink. It doesn't dry as quickly, but still dries out. I have to rinse the nib in water every time I use it.....must be the pen!

This ink was very nice! a little pricy for ink. I usually use the converter with many different quality inks but I wanted to use the cartridge sometimes so I ordered this ink and it was nice. I have only ordered the blue ink to try so far.

This product is as described and is of a very good quality. I would recommend it.

These worked perfectly with my fountain pen. They do release ink a little fast, but that could be my pen. I'm not sure. But the amount of ink that came in this order is definitely worth the price.

These cartridges were a complete waste of money. They were advertised as compatible with the fountain pen I bought but weren't. I am not happy that I cannot return them. The website description was incorrect, and they do not work.
