MONTBLANCREFILL BP B 2x1 ROYAL BLUE PF brand

I love how smooth these pens write. These refills were made by Mont Blanc and write just as good as the original ink cartridge that came with the pen. It actually fits another less expensive pen option which allows me to have the same quality writing experience without carrying the fancier pen around. Give it a try!

perfect fit - quality product

Very nice writing instrument.

Only problem is the ink dries on the tip and is not smooth like the factory Mont Blanc cartridge. Otherwise, once it flows, it is smooth as expected.

I though I had to change the cartridge for my pen because the one that was in it didn't work well. Turned out that the new one showed just the same problem. Conclusion: expensive product that does not work adequately therefore it is useless (why carry around a pen you cannot trust). I will try with an alternative manufacturer (which will most certainly be cheaper)

I always buy these and never had a problem before, but this time, the ink is a mess and its running out in less that 25% of its regular duration

Purchased these refills on a regular basis for several months without incident. The last two refill cartridges were defective. No response from the seller when I raised the issue.

I think it sat on your shelf too long.
