MontblancREFILL BP M 2x1 ROYAL BLUE PF brand

I have written with Mont Blanc pens for around 20 years. AND, I have used loads of other ball point pens to which there is always a degree difference in writing speed, pen durability, colour of ink, weight of pen. All factors into the style of your writing and how you feel about it. These refills are of the brand, tried finding a fault, but can't find any. These refill along with my Mont Blanc pen suit me fine. Colour is nice, the fluid of the ink is smooth, never had any air gaps, just a superior product. Must admit though, to try this product, you'll have to buy a Mont Blanc first. Bit of a costly recommendation, but if you're already a user, you'll know exactly what I mean... I would recommend this product...Enjoy!!!

Everything was as expected,. delivery on time

Very poor quality and does not last. The ink flow was intermittent and the refill ran dry after little use - not what I expect from this brand and price - very disappointed!

A fussy pen connoisseur, ink flow without scratchiness important. Consistent smooth flow & vibrant blue colour adds to the writing experience with this ink on all paper types.

If you are daft enough to buy a Montblanc pen product at silly prices because of joy of ownership (in all respects), buy these to do a genuine job.Thank you.

Terrible product. Appeared to run out in the first ten mins of use. If I scribble for a while the ink comes back but not reliable enough to use in a professional setting. My normal refills last years, not ten mins. Waste of money - and they weren't cheap.

Write smoothly. Very pleased

The right refill for the pen but it's quality in somewhat below that expected. Out of the packet the refill did not work and needed much coaxing with light heat, rubbing and scribbling before the ink made a mark. In fact far more coaxing was needed than anyone might think reasonable before throwing it out. Eventually the refill began to write but for how long and how reliably is a concern; expensive pens deserve better.
