5 Pack – MiniStar D1 Pen Refills (Black) – German Brand Made in Switzerland

I had a couple of nice pens that had pretty ordinary ink in them. The were light in color and rough to write with. I couldn't find replacement refills for them elsewhere. These work great, writes smooth and were a perfect fit.

Exactly what I needed. First one I tried fits and writes great!

Hard to find blue pen refill - now need to locate other colors - red, orange - for a 4-in-1 quality, gravity fed, unique "Quattro"

Product is exactly as described. Was a Longshot that it would work in the custom built pen that I was getting the refills for. Still I will find a use for them some how. Even if I just use the ink refills without a pen case. I like the colors and that they came so fast.

These refills are hard to find but they are the only ones I've find that fit my Rotring pen. They are smaller than most ink pen refills but they are well made and the writing is smooth, no skips, etc. Color options may be available somewhere else, but this set comes with, red, blue and black ink. Quality ink for a quality pen.

I had a multi color pen from years ago that needed refills. Took me a while to find the spec for these but they work great. Shipping time was a bit long but, apparently, they come from Europe. Highly Recommend

The D1 refills I ordered arrived quickly and were excellent quality. And shipping was free. They were a bit pricey compared to the competition but shipping was included, so it was worth it to get them relatively quickly,

This is an extra small size for a beautiful silver, Tiffany ladies, ballpoint pen.
