I bought a bottle of this stuff a couple of weeks ago and have been using it for all sorts of stuff... signing paintings and cards, writing notes to the milkman, a snail mail or two. But I decided I'd at least try to be a little objective aboutit. I mean, I know I like the colour because it's not too vibrant, it's sort of cool, restrained and tasteful. All the things I aspire to be but fail at miserably
My main concern is how lightfast ink is and how waterproof. First off, it's not too good on the waterproof front - a few sprinkles of water and the milkman has know idea how much extra milk I want. But lightfast? Wow

I wrote a sample and left it on a window ledge for an entire week in the sunlight. Today I penned another sample and compared them. Almost identical - near as makes no difference anyway.
I'll continue with this and compare the results at monthly intervals. So far, so good though. Pelikan violet gets my vote for looking good but just like them Gremlins, do NOT get it wet
