Features and Construction

This pen is defined by its measurable specifications and material choice, offering a clear, functional design.
Material and Build
The pen is constructed from a single stated material: high-quality plastic. This forms the entire barrel and cap, resulting in a lightweight pen. The plastic has a frosted, matte texture, which provides a subtle grip and reduces fingerprint marks compared to a glossy finish.
Size and Practical Fit
The pen's dimensions are precisely 13.8cm in total length and 1.1cm in barrel diameter. This size is typical for a standard fountain pen, designed to be comfortable for extended writing sessions without being overly bulky. The frosted texture can aid grip during use.
Uses and Placement

The pen's design and nib options make it suitable for a range of writing and drawing applications.
Event or Professional Use
With its clean, frosted aesthetic and choice of classic colours, this pen is suitable for professional environments where a discreet and reliable writing tool is needed. The consistent ink flow from the ink bag system supports steady writing for meeting notes or signatures.
Everyday Home Use
It serves well for everyday tasks like journaling, homework, or casual sketching. The option of a 0.38mm nib is particularly useful for detailed work or writing in small spaces, while the 0.5mm nib offers a smoother, more visible line for general notetaking.
Benefits and Buying Value
The value of this pen lies in its clear specification options and straightforward, maintenance-friendly design.
Reuse and Low Maintenance
The integrated frosted ink bag system is designed for simplicity. Once the ink supply is depleted, the user typically replaces the entire ink bag unit, which is a clean and straightforward process compared to some bottled ink systems, minimising mess and maintenance.
Why Choose This Product
You might choose this fountain pen for its defined nib size options (0.38mm or 0.5mm) and its no-nonsense plastic construction. It provides a specific writing tool based on your preferred line width, coupled with a practical frosted finish that resists slipping. The dimensions are clearly stated, allowing you to understand its physical size before purchase.
