Installation (Refill Replacement)
Follow these steps to replace an empty refill in your compatible PILOT pen:
- Disassemble the Pen: Carefully unscrew the barrel of your PILOT multi-function pen to access the internal mechanism. For most compatible models, this involves twisting the pen body near the grip or tip.
- Remove the Old Refill: Identify the empty BVRF-8F-B refill. Gently pull it out from its housing. Note its orientation for correct installation of the new refill.
- Insert the New Refill: Take a new PILOT BVRF-8F-B refill from the pack. Insert the new refill into the designated slot, ensuring it is fully seated. The narrow tip should point towards the pen's writing end.
- Reassemble the Pen: Carefully screw the pen barrel back together until it is securely fastened. Do not overtighten.
- Test the Refill: Extend the pen tip and test the ink flow on a piece of paper to ensure proper installation and functionality.

Operation
Once installed, the PILOT BVRF-8F-B refill operates as a standard ballpoint pen refill. Extend the pen tip using the pen's mechanism (e.g., clicker or twist) and apply light pressure to write. The 0.7mm fine point delivers a consistent black ink line suitable for various writing tasks.
