Pilot BRFN-10F Ballpoint Pen Refill

Pilot BRFN-10 Refill

The BRFN-10F is a plastic body Pilot refill that is found in the Dr. Grip pens as well as the Pilot Ageless and S20 executive pen. It’s a proprietary shape that only Pilot uses, which makes this refill difficult to swap out in place of another refill. The BRFN-10 is not sold in an extra fine model, for that you need to upgrade to the BRFN-30EF.

Pilot makes a higher end refill in the same shape: the BRFN-30F.

The BRFN-10F is technically the Acro ink BRFN-10 refill in the F (fine) size. For this line of refills fine is 0.7 mm. The refill is also sold as the BRFN-10M, which is a 1.0 mm refill.

Acro ink is sold as a ballpoint refill because it’s oil-based, but it’s more commonly accepted as a hybrid ink because it’s a modern, lubricated oil-based ink.
