FisherSpace Pen - 3 Pressurized Cartridges Blue Ink Fine Point #SPR1F

Have 3 Parker pens that needed new cartridges. Have used these refills before and one that I purchased previously and have left in my car here in hotter than heck South Carolina for about 2 years now writes every time, does not leak, writes immediately. Consistent performer. There were three separate individual packages that came with the Parker adapter. Would buy again.

These cartridges can be stored for years and still write the first time it's used, unlike manufacturer's products that will dry out after a couple of years and no amount of coaxing will convince them to perform the task they were created for. (I keep a supply on hand for my various pens because the rule is that one always runs out of ink at a critical moment, and it's too late to go shopping for a replacement and even Amazon 's delivery is not going to salvage that moment in time.)

Good product, writes on anything

Product was here in the short amount of time as promised and the correct product had a good price.

I am a true pen afficianado, always on the hunt for the "perfect pen." The Fisher refills come pretty close. I have them in my Sensa pens which makes for a double whammy of smoothness. What I love about these refills is that there is now pooling or smudging of ink! Close to perfection!

First one I installed worked great, very smooth, beautiful royal blue color, great water resistance, until I did a bunch of carbon paper work (yes we still use those). I've noticed this before with fine ballpoints, for some reason I can't fully identify, if you use a fine ballpoint pen on carbon paper, it will not write the same afterward-- I think the carbon gets in the ball mechanism and gunks it up, and once that happens, you cannot undo it with any of the usual tricks. I was hoping the pressurized special formulation ink of these would hold up against this, but they are no different, which is disheartening as they are quite expensive. I have not noticed the same thing with medium points-- I'm guessing the larger mechanism is less prone to clogging--, but medium points come with their own set of drawbacks. Alas, I will have to live with the drawbacks of medium points to boost reliability. Just be aware they write on *almost* anything in *almost* any condition, but if you write with them on carbon paper enough, they won't write much longer, so use a pen you don't care about on those.

Love these pens. I give them as gifts. refills are for the fine point and they are just fine.

First cartridge broke in half and leaked all over me prior to putting it in my pen. Enough said.
