Pen Tip (Nib) Design & Engravings

The stainless steel nib design is the hallmark of the Kakuno series, engineered to make fountain pen writing approachable and easy to check:

• The "Winking" Smiley Face: Engraved directly on the face of the nib is a playful, winking smiley face ($v\underline{\circ}$).

  • Functional Visual Cue: The engraving serves as a quick orientation guide—if the smiling face is looking straight up at you while writing, your nib is at the ideal writing angle against the paper.

• Nib Size Options (Soft Yellow SY):

  • EF (Extra Fine): Extremely crisp, fine lines—ideal for compact calendars, detailed planner spreads, and tight grid lines.

  • F (Fine): Excellent all-around size for everyday note-taking, journaling, and letter writing.

  • M (Medium): Broader line width that offers smoother ink flow and highlights ink shading characteristics.
