Platinum Carbon Ink Cartridges - Black

This is the best permanent black ink for pen and ink and with watercolors. Fast drying, deep black. I use in a high end Platinum pen with an UEF tip and love the combination.

So I may or may not have attempted to suction the ink out of this cartridge to put it into a converter for another pen. And this may or may not have been an absolutely terrible idea that left me with black rims on my fingernails that will not wash off.So while I can’t say anything about how it writes, I can say it’s a beautiful, striking black color, long lasting, and waterproof! If you need last minute dark nails for your Halloween costume, honestly, give it a try!

Quick service for a great water resistant black ink. I’ve used it in fountain pens for a long time. Cartridges are convenient and no mess!

Very reliable ink cartridges. Love them for line and wash work. Let it dry and no smears or reactivation. Recommend.

I’d say this ink is water resistant for the most part, but definitely not completely waterproof like the Platinum Pigment Blue cartridges. These aren’t cheap! Over $1 per cartridge. The Pigment Blue is $7 and some change, and you get 10 of them in a box.These work well in my Perpanep (Platinum x Kokuyo aka Preppy.) They have never clogged, thanks to Platinum’s amazing slip-and-seal cap.

I love that I can swap out the original ink in my Preppy pen with this ink. It is totally waterproof once dry and works great for my urban sketching.It IS very, very dark black ink, trust me!

I use a Crown Fountain pen for ink sketching when I'm outside making nature sketches. I always use this ink because it is a true dark black and it is waterproof so I can add watercolor paint to my sketches later. It dries quickly and I have not had any bleeding of the ink when I put the watercolors on after I get back inside. There are specific ways to make quality ink and this brand meets all of those. I bought the cartridges but this same ink also comes in bottles if you use a dip pen or a fountain pen that you manually refill. It is my favorite ink so I definitely recommend it.

Great ink in a convenient format if you want to avoid the mess that this ink can make in bottle form.
