PlatinumCarbon Ink Cartridges - Black

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!

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!

If you give this ink enough time to dry it deals well with water making it good for watercolor or even putting dye based ink on top of it. I tested on Midori paper. Itried Rorhrer & Klinger SketchInk first because I heard that carbon black can smear, however it seems a gentle touch makes Carbon Black just as good

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

Sorry, I don't "love it" inanimate objects, except my car and gun.Strange that this ink is here directly. Supposedly, it was only available in Japan after September 2016, but I'll take it.Yes, it does dry fast. Even when it still looks wet on some surfaces. I bought it to use mainly on cardboard (VERY SMOOTH) holders for coins. Pigment is archival and none of the Sharpie bleed/fade/discoloration.It is not PURE carbon or it would be dark, dark brown. But, not a problem.Going into the Platinum 3776 Century was a little tough. Although it does not screw in, twisting while inserting is necessary. My first time actually shot ink out of the nib before I learned the trick. This is a very smooth ink on bond paper (my 28# test stuff.) The Japanese M nib flows a little too well though. Time to go F or SF.I bought the four pack just to be sure before spending a huge amount on a bottle. A bottle of this ink is next!

I like the convenience of a cartridge combined with the nature of a waterproof ink. But as I said in the headline wait until it dries before washing over with watercolor for best results. It works and has been my "go-to" sketch ink as it doesn't damage nibs and it has the ball in the cartridge which helps with a quick start on the pen with a shake if you've let the pen sit for a couple of days between uses.

Good price, quick delivery

Even though this was on my class materials list I resisted buying it from memories of leaky fountain pens, but I was encouraged to try it and it is now my go to pen for drawing with permanent ink. You DO have to push the cartridge in firmly until you hear & feel a real CLICK. I thought I had installed it correctly, even viewed a web site on it, but became frustrated that I could not get ink to come out. As a last ditch effort I looked at the reviews again searching for some advise and there it was (thank you). I opened it up and gave the cartridge one more push. LOUD CLICK. Yea!! The more you use it the more comfortable you will become with it. I'll sometimes switch to micron .005 & .01 depending on where I'll be sketching, and how much gear I want to bring.
