Experience ultra-fine precision and minimalist elegance with the Uni-ball One F Retractable Gel Pen 0.38mm. Designed for fine-line writing, detailed note-taking, and journaling, this pen combines a sophisticated muted "faded" barrel design with elite Japanese writing technology.

Featuring Uni-ball's signature pigment gel ink, it produces clean, crisp, and deep black lines that dry instantly to prevent smudging or feathering. The integrated metal tip stabilizer shifts the pen's weight toward the tip, creating a lower center of gravity for balanced, effortless strokes with zero pen wobble. Finished with a sleek, spring-loaded wire clip, the Uni-ball One F is both a high-performing instrument and a stylish everyday carry staple.
