Schmidt 635 Mini Ball Pen Refill - 6 Pack - Blue

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.

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.

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.

The color was a bit light and faded, trued to return it after a day of consideration and found that returns were duasaloud by the seller, despite having returned the red version in the past.

Was not the right color or size. Not compatible as stated. This is happening more frequently than it should. Convenient of Amazon has been lost by having to return so much.

Exactly what was needed for my wife’s purse pen

The ink comes out just fabulously smoothly - its such a joy to write with it because oil-based ink usually cracks as one writes but these don't! Bought it for my Swarovski pen, and the fit was perfect.It would have been better if the refills came with a stopper at its end, that will help to make keeping them a lot less messier. Ink leaks.

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.
