Features and Construction

The pen's construction focuses on delivering a reliable line for creative and everyday tasks. Its design parameters are clearly defined, offering users a predictable tool size and weight.
Material and Build
The pen shell is constructed from plastic, providing a durable yet lightweight casing for the internal ink mechanism. This material choice contributes to the overall net weight of 9.5g per piece, making it easy to carry in pencil cases, art kits, or pockets. The black ink refill is formulated to be waterproof, a practical feature for artists working with watercolour washes or anyone needing smudge-resistant lines.
Size and Practical Fit
With a body length of 133mm, this needle pen fits comfortably in hand for controlled line work. This dimension places it within a standard size range for detailed drawing instruments, balancing enough length for grip stability with compactness for storage. The weight distribution from its 9.5g mass supports precise tip control during sketching or writing sessions.
Uses and Placement

The pen serves dual purposes in artistic and practical contexts. Its specification as a tool for 'painting, writing' indicates versatility across different mark-making applications.
Event or Professional Use
For professional illustrators, comic artists, or designers, the waterproof black ink provides a reliable medium for final line work, concept sketches, or storyboarding. The syringe cartoon design could align with medical illustration themes, graphic novel aesthetics, or simply offer a distinctive tool appearance in a studio setting. The pen's consistent line quality supports detailed technical drawing or annotation tasks.
Everyday Home Use
At home, this pen functions as a general writing instrument for journals, planners, or correspondence where waterproof ink is beneficial. Students may use it for note-taking, diagram labelling, or art homework. Hobbyists engaged in adult colouring books, bullet journal decoration, or casual sketching will find the fine line suitable for intricate patterns and details.
