Zebra F Ballpoint Old Metal Body (F, M, B) Refill

• Length: 88.9mm (3.5″)
• Manufacturer’s website: Zebra

The Zebra F Ballpoint metal body refill is a proprietary size and shape that fits some Zebra ballpoint pens. It has a similar profile to the Fisher Space Pen compatible refills, so it will fit in some other pens of that profile. This refill is available in black ink in a fine, medium, or broad line width. The F refill also comes in a new plastic body version.  No third party refill makers offer a substitute for this refill.
