(Pen Description)

The Eboya Hakobune (Large) – Kogetsu Yellow is a handcrafted Japanese fountain pen made from Eboya’s original color-marbled ebonite. The Hakobune features a traditional barrel-shaped design with no clip, giving it a clean and understated profile. The name “Hakobune” (方舟) refers to a rectangular boat, which inspired the shape of the model.

The Kogetsu Yellow (江月) finish combines a deep black ebonite base with a distinctive yellow marble pattern. Eboya describes “Kogetsu” as referring to the image of the moon reflected on the surface of water. Because the marbled ebonite is produced and finished by hand, each pen has its own individual pattern and texture rather than having an identical printed finish.

As the Large version, the Hakobune measures approximately 150 mm capped, with an 18 mm cap diameter and 18 mm barrel diameter, giving it a substantial full-sized profile. The ebonite construction also provides the characteristic warm, slightly tactile feel of hard rubber, while the carefully polished surface gives the pen a smooth finish.

The Hakobune Large uses an international-standard cartridge/converter filling system and is fitted with a Bock #6 14K gold nib, available in Fine, Medium Fine, Medium, and Broad configurations. The combination of its substantial dimensions, clipless design, and black-and-yellow marbled ebonite gives the Kogetsu Yellow a distinctive appearance while retaining the straightforward, practical construction of the Hakobune model.

(Pen Nib)

The Eboya Hokabune  (Large) is fitted with a Bock #6 14K gold nib in a Medium (M) configuration. Eboya lists the Large Houga with a Bock #6 14K gold nib and offers Fine, Medium Fine, Medium, and Broad point options.

The 14K gold construction provides the nib with good corrosion resistance and a degree of natural resilience. It is designed for controlled, consistent writing rather than being a flex-oriented nib, giving the writer a stable writing point with a responsive feel under normal writing pressure.

The Medium Fine point sits between a Fine and Medium width, making it a versatile choice for everyday writing. It provides more ink presence and smoothness than a very fine point while remaining sufficiently narrow for detailed handwriting, notes, and general correspondence.

The Bock #6 format is appropriately proportioned for the substantial 18 mm Large Houga, giving the pen a balanced appearance and a substantial writing point. Together, the 14K gold construction and MF configuration provide a practical combination of precision, smoothness, and controlled line width.
