Kokuyo WP Finewriter Pen Refill - Blue Black

The replacement refill for the WP Finewriter, in blue-black. Because the Finewriter's resin capillary tip is built into the refill itself, each replacement restores both the ink and a fresh writing point — so the pen never develops a worn or splayed tip the way a fixed-point pen eventually can.

Notable

• Includes the writing tip, not just the ink — every refill is effectively a new point
• Same blue-black ink and fine line as the pen ships with
• Drops into the WP Finewriter body; no tools needed
