2009-10-26noodler's ink along with my purchase of a new fountain pen, i bought some new ink.
i kept hearing about noodler's ink, with their bulletproof black. since i was running out of the parker quink that i'd been using for a while, i got a bottle of the noodler's to try it out.
i also did a rough test of the waterproof properties, comparing the two inks. the paper was submerged briefly in water:
wow, pretty good.
at $18 a bottle, i found the noodler's a bit pricey. but it turns out that the bottle is large (3 oz.), so the value is quite good, with the same cost per ml as the parker quink.
