4 Pack - Ball Point Refill - Black Ink Medium Schmidt P900 Parker Style

fits pen and writes very well. great price for four refills.

4 cartridges which work well

Very good quality and value for the money

They just seem to be as good as the original in my pen, so I’m very happy with their performance. Seems to write smooth.

Was just delivered a day a go. So far, so good.

I got these as refills for a couple of pens that I made. This is the second time that I have bought them. They are pretty good quality though I feel like they don't last quite as long as the brand name. I do think they are a decent value for the price and the ink quality is good. I would recommend them as a decent refill.

I have used these for many years. They are my go-to refills for pens that require this style of cartridge.

It's a ballpoint refill and it does what a ballpoint refill does. I use these with my overpriced ridge pens and it works great.
