Outus 12 Pieces Black Ink 1.0mm Medium Point Metal Ballpoint Refill Set for Retractable Pens

Really good quality for a low price - I was really pleased with these.

Fast delivery, fits properly inside the pen, it does its job, Thank you

Fits Parker pen Writes well

Writing and drawing are fine

I have used these to keep using a Cath Kidston Pen I was bought, fits perfectly and the pen twist mechanism works with these as well. These do NOT fit with the Swarovski pens, they require a smaller one in length even though the ball point is the same.

Received ball pen refills this afternoon. 'JUST' put 6 refills in 6 different pens and they seem to work fine. However, you must remember to remove tiny protective cover on the tip.

Have a few pens that take this type of refill and really like these. Excellent ink flow straight out of the box and enough to keep me going for some time.Fit my pens no problem and great replacement for the originals. Fits Parker pens and well worth the money. Recommend.

Really useful product that works well in several different brands of pen. Good price and great quality for that price.

I have an old tac pen that finally needed some new ink cartridges. It normally takes Parker cartridges but with the price going from 2 dollars to 10 I felt that it was time to find a substitution. These cartridges get it done, they fit perfectly and the ink writes well. The only issue that I had was the rubber that they place over the nib can be very hard to get off. Other than that they are great. Why pay 10 dollars for 1 when you can get 12 for 5. It's essentially the same thing.

Just received my refills. 12 Parker jotter refills for $6 is one heck of a price. I just tried one in my pen and the fit is fine and the ink appears to flow smoothly. I am very satisfied with the purchase. The only question will be durability - how long will the ink flow, will it continue flow evenly and will the cartridge leak. For now, I'm very happy with the first of twelve. I will update when, and if, things change.

I’m very pleased with these ink replacements. My company gave me a pen I actually like and I was disappointed when the ink ran out. Thought I would give this a try, wasn’t sure if it would fit or not. They are easy to use and write great. They actually fit in several pens I had around the house. I recommend them!

Better than expected. Very smooth and consistent. Will buy again.

Perfect refills for my pen. Great price.
