CaoDuRen 3.88 in/98 mm Long Ballpoint Ink Refill Compatible with Montblanc Ballpoint Ballpen Rollerball Pens Tip: 1.0mm Medium Point, Soft Smooth Roll,116190 124493 P164 (Black, 12PCS)

Well I've always used the Mont Blanc refills in the past but they were never great the ink would skip depending on the media I was using and mess up my signature when signing documents, so I stopped using it. So, I'm big on USA product if I can get it, and when I saw this refill was USA I thought it was worth a try. And as it turned out it was a great buy, of course I can't comment on the longevity of the refill, but when I saw that the tips were protected with a wax substantiate when I received them to protect the ball tip, now that's a nice touch and a manufacture that is proud of their product. The ball pen glides effortlessly as you write... made my Mont blanc pen the best I've ever, better than new.

These cartridges are 100% better than the original Mont Blanc cartridges. The original are very scratch y. The ball point refills are super smooth. I highly recommend them especially for the cost.

I have used Mont Blanc refills for nearly 30 years. If I didn’t know better, I’d think this refill was actually from Mont Blanc. It’s great to get the same quality for such an inexpensive price!

I bought non-Mont Blanc refills for my ballpoint Mont Blanc pen. My biggest concern initially was, would the refill actually fit the pen. It fit beautifully and I am very pleased with the ink quality, as well!! It cost 1/3 of the Mont Blanc price...a very nice bonus!!! Super pleased and would enthusiastically recommend!! Thank you so much!!!

Had to return because the ink refill sent is too small for the Montblanc Meisterstueck Roller Ball. Does not fit.

These refills are good quality for a fraction of the cost of Mont Blanc's refills. Mont Blanc refills are out of line cost wise.

While these refills fit the pen perfectly, they last 1/3 the time of the MB original.

They write smooth

Es ist schon Wahnsinn, wenn man sich einen Kugelschreiber für 400 Euro kauft - aber was soll man tun, wenn man einen solchen unbedingt haben will? Ja, und nun habe ich ihn halt - und er gefällt mir!Aber Minen sind Verbrauchsmaterial – die müssen NICHT zehn Euro kosten, oder mehr! Diese hier kosten viel viel weniger, und die sind genau so gut!

Schreiben toll, mittel stimmt auch, kaufe wieder.

Fit perfectly, writes well.
