5 Pack – MiniStar D1 Pen Refills (Blue) – 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.

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.

So happy! They fit my bullet pen! Each one is clearly labeled, in case I forget the details or forget to come back here to look for them.

The last refills like this I bought started to skip shortly after I started using them. So far, these are much nicer. Smooth writing and got my Rotring multi-tip pen perfectly.

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

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

Pencils work great. Black lead good. Colored leads were wet in packaging and unusable. However, wanted mainly for black so not consider returning.

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,
