Kaweco D1 Ballpoint Pen Refills 1.0 mm Black Pack of 5 | Ball-Pen Refills for Sport und Liliput Series | 1.0 mm (Medium)

The ink is of nice color and smooth, consistent line. Price is reasonable for what you get. Definitely recommend.

Replaced a Swarovski Crystal pen ink. Good in every sense. Will buy again if needed

Excelente

I wasn’t sure if I would like this or not since it is 1.0 size, but to my surprise, as you can see from the picture, it is almost identical to the size of the zebra .7, a tad bit bigger but not as big as most 1.0. They fit well in a cross, last a while and write good. Although I prefer the zebra gel, they don’t last long enough. I would definitely buy these again.

It can be difficult to find size D1 refills that go into "mini sized" pens. When I found these, I was looking for a gel type D1 refill for a couple of small pens I own. These are a medium black refill that's almost as bold and smooth writing as a gel style refill would be. I would highly recommend these refills. Smooth writing, no skipping, or drag, a 9 out of 10 compared to a gel refill. These are now my "go to" refill until some over paid pen clown decides to make,and come out with a D1 size Gel Pen refill! No offense intended to any of you over paid pen clowns out there.

if you like the pen, the refill is required (and inexpensive)

bought for my wife's multifunction pen very sporadic performance quits writing with no warning wife is NOT HAPPY purchasing a different brand from a more reputable manufacturer

I am a big Kaweco fan. Have a lot of their fountain pens. Got my first ballpoint Kaweco. The ink didn't last long. I got these refills, the first one didn't work at all, so one out of 5 was a waist. I am not sure how the rest will hold yet, but so far not so good.

Los tres productos seleccionados me llegaron mucho antes de la fecha prevista, en muy buenas condiciones y cumplen totalmente las cualidades que yo tenía previsto.

Fantastic refills for recently gifted and new favourite pen! Bought size 1.2mm which writes beautifully. Box differs from that shown on the listing but all good and very pleased!
