Uni-ball One F Gel Pen 0.5mm – Low Centre of Gravity | Made in Japan

The F in uni-ball One F is for the redesigned body: a stabiliser mechanism drops the centre of gravity toward the tip, so the pen sits still in the hand and stops wobbling through long writing sessions.

• 0.5 mm ball with uni's dense pigment gel ink — black ink in both barrels
• Low centre of gravity stabiliser mechanism; knock type
• 139.5 mm long, approx. 14.3 g
• Two barrel colours from the Japanese seasonal palette: Hashizuku F Green (葉雫, "leaf drop") and Shimobashira F Blue (霜柱, "frost column")
• Takes the UMR-05S refill — Made in Japan by Mitsubishi Pencil (uni)

Two things worth knowing: both barrel colours write in black, the colour is the body not the ink. And this is the pen — it takes the UMR-05S refill we also stock separately. Shipped from Sydney, Australia.
