Parker Compatible Ballpoint Pen Refills Work for Most Brands Pens with Smooth Writing, Waterman Compatible Spring Refill Replaceable Twist Action Medium Point Refills 1.0mm Pack of 15 (Black)

This is my second order of these refills as I wanted to get more prior to any price increase. Pros: Price these refills are less than a dollar a piece and I call that a big win for anything of this quality. On normal paper I have found these perfect for my style of writing. Also seeing as these are 1mm wide width you can actually vary the width of the line with tip pressure which is something I find very handy while writing my daily morning pages. Fit my pen with no problem. Note though as these come with springs attached (a nice Plus) be sure to remove the spring from the refill should their be a spring in your pen that you want to use for the refill that or remove any spring in pen prior to inserting. I was so excited by getting my second batch I had to test one right away and ended up with two springs in my pen so it would not work until I removed one. As pen springs can get lost easily it is great that these do come with springs attached. Oh lastly I like the packaging as it does not have every pen on a separate card, but all in a nice case about the size of a CD single case. Cons: None that I can think of at the moment. Yes I'd buy these again and recommend them to friends.

Received 3 cool pens from my son for Christmas last year and one of them ran out of ink. Searched Amazon and found these cartridges that matched what was used in my pens....worked perfectly and we're back in business :)

These are great, the work as intended

Great pen refill! Works as well as the big name brands at a fraction of the price. The ink is very smooth and flows nicely. I also like that the refill comes with springs making it easy to install fresh ink. I will be buying more when the time comes

I don't know what "sheerness" so I'm rating it a 4/5 for that. You're never quite sure what you're going to get buying off-brand. These were surprisingly very good. They fit perfectly, the ink flows smoothly and doesn't smear or smudge (which can be more of a problem if you're left-handed). They've got a little heft to them so the pen isn't too light and so far I haven't had an issue with them drying out. I didn't really need this many refills at one time, so whatever I have left is just sitting in my desk. They seem like they'll keep for a while. The writing is clear and easy to read, not too light or spotty. It's not bleeding through the paper and as far as value for money, these were a great deal. Usually an individual refill will run me $3-4 each, so for the price of about 3 I got a bunch of extras.

I just got the item recently, so I really can't say anything about the longevity or value of the pen refills. I had asked a question a little while back about whether this refill would fit my Sheaffer twist pen, replacing the K-style refill. Another question had been asked by someone else concerning the same brand of pen, and the same kind of refill. My question never did get answered, but I went ahead and ordered this 15-count refill set anyway. The other questioner was told the refill would fit the other pen, so I took a chance. It turns out that the Nekigoen refills aren't meant for the Sheaffer twist pens. But on a positive note, I happened to have three other pens that these refills fit perfectly. Two are Adler brand promo pens from an insurance company, the third I dont know. So it turns out that it was a good purchase after all; I really liked those particular pens, and was disappointed when they ran out of ink. So all in all, so far, the refills work for my other pens. Smooth writing, no globs of ink left behind when I write. They work for me. I like them.

Nice refills! I purchased a 2nd set.

Fit my favorite pen perfectly. Now I have a lifetime supply.

Perfect fit for my 15 year old spring twist pen. First replacement, and my beloved pen writes even better 🥰 ty

I am very happy with my purchase. I bought this refill by taking the advice of another reviewer. I carefully measured the ink refill and studied the picture in comparison to the one I had. I also liked that the manufacturer provided springs with each refill. I lost my spring a while back and was using one I cut to size from another pen, but it wasn't working well. My pen now works as well as when I got it and I can now use my favorite pen again.

I was very pleased with this product it fit all my pens!
