Monteverde Fountain Pen Ink Cartridge for Lamy - Burgundy - Pack of 5

This is decent ink--seems to be safe, doesn't clog, etc. It's not the most excitig color, but not too bad. It certainly is has a bit more saturation than Lamy. The best part, however, is that the cartridge fits Lamy pens, but also standard international pens if you flip the cartridge around. Very clever.

Thanks to JDS for the hint to reverse ends of the cartridge. I thought it did not fit my Lamy Safari until I saw that. Big end for Lamy, small end for international standard.
I find this flourescent orange is best suited for hiliting or underlining unless you make use of the flourescent feature.

I'm using this ink with a Safari, and it flows just as perfect, no blotches and able to produce a thin line with a Extra Fine nib. So far, I prefer this than the Lamy ink.
