The Pilot BVRF-8F, sometimes known as the RF-8 Fine, is a Pilot standard sized refill which is part of Pilot’s Acro line of hybrid inks. In some product descriptions this ink is called a ballpoint ink, but it’s actually a hybrid ink. (Hybrid inks are oil-based so some companies classified them as being ballpoint, but we at Unsharpen believe in making the distinction.)
The Pilot BVRF-8F is 0.7 mm where the Pilot BVRF-8EF is 0.5 mm.
This refill is included in Pilot’s Dr. Grip 4+1 multi-pen, the Pilot Evolt 2+1, the Pilot Acro 4 Color, and a number of other multi-pens from Pilot.
The Pilot BVRF-8F is a plastic-body refill that is similar to a D1 refill, but longer and does not adhere to ISO standards.
