Pilot BRFN-10F Ballpoint Pen Refill - 0.7 mm - Black

These are the best refills I have ever ordered. I could not be more pleased with how smoothly they write.

These are great refills. While not specifically referenced in the JetPens catalog, the ink seems to be a low-viscosity ink that flows much better than traditional ballpoint ink. It is comparable to Uni "Jetstream" ink. I find the Pilot ink actually flows onto the paper more smoothly and will less skipping than Uni's "Jetstream" pens.

These refills are write so nicely. It is so much better than the ones sold in the US. This was an awesome purchase.

I ordered these as refills for my American Dr. Grip Center of Gravity. The ink flows smoothly and I love how it's a .7 tip. There is no way to buy the .7 tips at American stationery stores. Will repurchase!
