635 Mini Ball Pen Refill - 6 Pack - Blue

I ordered these refills for a pen that I have been using for 20 years and refuse to give up. I wasn't expecting much because I was ordering 6 refills for the price I used to pay for one. I couldn't have been more pleased. These pen refills write better than the name brand refills I used to get. The flow of the ink is smooth and it feels firm, which I really like. In addition, I received 2 free refills from Bertram's Inkwell, which was a very nice surprise. I highly recommend this refill if you're searching for a good replacement.

Perfect fit on my wife's Swarovski pen. Writes better than the ink that came with the the pen from the factory.

I was given a mini pen as a present and have been looking for a refill that fits for 2 years, This refill fit perfectly and I can now use my fancy little pen again. The refills write smoothly and I received the order in a short period of time considering it shipped from outside the US. I am completely satisfied.

Good replacement. Ink quality isn't as great but plenty good to get the job done

I’ll admit that I tried these D1-styled refills because I have been quite happy with the company’s Easyflow ballpoint refill (the one for ballpoints that use Parker-style cartridges). I have gotten and used the black, red, and blue colors. Of the three, the blue is the best: It’s the brightest, boldest, and most consistent ink; once I start a new cartridge, it’s always there when I start to write. The black color is dark, but it requires some start-up each time I use it plus some cartridges will railroad from time to time. Of the three, the red is the worst: It’s rather weak and light in color and also seems to be the scratchiest on paper.

Ahh those damn mini pens. So hard to find replacement ink for them. Forget Office Depot and others they just look at you funny requesting this specialty product. I purchased a neat stainless steel pen from Best Buy that is also works a Laser Pointer and a Stylus Pen. I use this pen with my Tablet to scroll webpages and select items on the screen. In about a week the Black Ink stopped working and I looked everywhere for a refill. Look no further German Made replacements found on Amazon. Next I prefer blue ink. Yup-Amazon had 'em. Now next time I need a refill I point and click with my pen! Thanks Amazon and shipper who got this to me promptly.

These fit my favorite pen and work well. What else is there to say?

Good refillls, good seller.

I have to make circles on a piece of paper everyday for them to flow

Only refill that fit the Swarovski pens (that I am aware of). Works well, just not very long-lasting.
