"In my opinion, this is an excellent black ink.Pros: * Reasonably quick drying (not fast, but faster than some of my other inks). * Smooth writing. * Extremely black ink! It is made with carbon microparticles which makes it very black. * Waterproof and fadeproof (an earlier test of this ink has been sitting the sun for close to a year and hasn't visibly faded)Cons: * When the bottle is full, the internal reservoir doesn't work very well. * This is a rather expensive ink. * As a pigment ink, you can smudge it even when it is dry. It doesn't smudge easily but it is possible. * If it dries out or comes into contact with other inks it turns into a sludge that can clog up your pens. Regular cleaning and a pen that doesn't dry too quickly is essential."

If you are looking for a proper black permanent ink this is ideal.Not great for day to day use unless you are requiring something permanent for signatures etc - maybe get a cheap chinese pen especially for it that youre not worried about ruining.nigel ward
Best black ink ive bought. Waterproof. Brilliant for sketches with no fade.

I read quite a few reviews before buying this ink and am glad I did based on what I read about others.I love fountain pens and spent much of my adult life avoiding them because I had it drummed into me at school (Primary in the UK) that as a left hander, my writing was terrible and always smudged. It took me way too long to realise it was the fault of the ink and choice of pen back then, not the writer.So, armed with my new Lamy Safari, I loaded up the Lamy converter (alternative to ink cartridges) Platinum ink and tried writing. Wow! For the first time in my life, I can write with a fountain pen, dragging my hand over the page as I go, and not see a single smudge. Believe me, I have tried. The ink dries so quickly, that it doesn't smudge at all. It's a revelation to me as a huge fan of the idea of writing with a fountain pen and never having been able to do so successfully my whole life.I'm extremely happy with the Platinum ink and the little gadget in the bottle to make it easier to use a plunger style converter makes all the difference. The ink dries almost instantly and is a deep black colour on the page. It's beautiful to write with.cnandrade
Very good ink. Use it in Lami Safari, dries very fast a very good waterproof.
