Graf von Faber-Castell Ink Cartridges, Box of 6, Cobalt Blue (FC141101)

Very pleasant red. A deep pomegranate type of color. Is not waterproof.

these cartridges are an excellent way to enjoy these inks! this one is a nice deep maroon. will probably get a full bottle soon.

Love this color Blue!

This is a great blue ink. I love how intense it is. This is not your dull, ordinary blue; however, it is still well behaved.

Arrived just one week after ordering. The refills snap right in, no mess or hassle, and the ink is beautiful

I overlooked that this was only a 6-pack. Or I didn't overlook it, and just expected larger cartridges. Who can remember? Either way, this was the tiniest little pack of the tiniest little cartridges. The thing that's really wild is that I've been using my Faber Castell on and off all week for serious notetaking, and the tiny little ink cartridge is still like half full. I don't know how they pull that off.It's a shame the pen doesn't take generic cartridges (which are larger, by the by) but the ink itself is of a very nice quality and again, it just seems to keep going and going.

This is a beautiful color if your fountain pen uses cartridges. Mine does and I love these FABER CASTELL pens and their ink colors.

Great burgundy red on paper.
