Pilot Acroball Ballpoint Pen Black Ink Refills, 0.5mm, BRFV-10EF-B, Set of 6 (Japan import)

This was a great buy! I'll definitely buy again when I run out with won't be for a long while! I write and sign for my job all throughout the day. Same size gel cartridge lasts me a week. 1 month and I'm still not 1/4 through one of these cartridges. The tip is precise and the ink drys quick.

When it cones to pens its a personal thing I'm very pleased with the this product. 0.5 fine point is perfect for every day use. Ithe ink does not smear or run. If you like fine lines writing tool this is a good choice.

The media could not be loaded. one of them broke

Fits perfectly.

I bought this pack a while back when I bought my Pilot Acroball 4 pen. Until now I am having to replace the black and blue ink cartridges. The replacements are intended for BREV-10EF-B (0.5mm) and I was looking for BVRF-8EF. Anyway, the barrel is too big for my pen. However, if these are the ones you need, they are a very economical price! Make sure that you get the correct type, the correct COLOR, and that you can replace the cartridge. (I'm on youtube and I can't find a video that will help me without breaking the whole pen! :/ ) It writes nicely, doesn't bleed, doesn't go blank as you write as is the case with other pens.

Great value!!

This is my second time ordering these because the first ones I ordered were great. However, this time they were terrible. It started nice but not even halfway through it started streaking. Horrible! And I ordered a lot. Will never do that again. I was going to give some to my colleagues. Thank goodness I tested them first. So disappointed and angry! And I just missed the deadline for returns by 3 days! Save your money and your peace of mind.

Pilot pens have never disappointed me. Great pens.
