Product Overview

• Model Line: Pilot Kakuno Series

• Specific Model: Soft Blue (SL) from the pastel white-barrel collection.

• Design Aesthetic: A clean, modern look pairing an ivory/off-white hexagonal body with a gentle pastel-blue cap. The hexagonal shape is structurally designed to provide a comfortable grip and prevent the pen from rolling off flat desks.

Pen Tip (Nib) Design & Engraving

The standout, signature feature of the Pilot Kakuno line is its uniquely designed steel nib, which is purposefully crafted to make writing approachable and cheerful:

• The Kakuno "Smiley Face": To help beginners maintain the correct writing angle, the top side of the nib is engraved with a charming, winking smiley face ($v\underline{\circ}$). When the face is looking directly up at you while writing, the pen is in the perfect position.

• Nib Size Availability (FKA-1SR-SL): As indicated by the product chart, the white-barrel soft pastel series (including the Soft Blue SL model) is highly versatile and supports three distinct nib thicknesses to match different handwriting styles:

  • EF (Extra Fine): Perfect for ultra-precise, compact writing and detailed scheduler planning.

  • F (Fine): The standard, daily-use standard size that handles regular note-taking flawlessly.

  • M (Medium): Offers a smoother, broader ink flow that highlights shading properties well.
