Features and Construction

The pen is built around its core function as a precise writing and drawing instrument. Its construction and specifications are defined by the materials and dimensions provided in the source information, focusing on practical utility.
Material and Build
The primary construction material for the pen's external casing is plastic, forming the shell. This material choice contributes to the pen's lightweight profile, with each unit having a net weight of 9.5g. The build incorporates the functional components necessary for a needle pen, including the ink delivery system, which is supplied with black ink. The hand-drawn cartoon syringe design is a visual feature applied to this plastic body.
Size and Practical Fit
The pen has a total body length of 133mm, a measurement that influences its grip and balance during use. This size is typical for detailed work requiring control, such as sketching or technical drawing. The dimensions and weight are consistent with a tool meant for precise application rather than broad strokes, aligning with its stated purposes of painting and writing.

The black ink provides high contrast on various surfaces, suitable for creating lasting notes or preliminary artwork. Its specific design may appeal in contexts where a unique or thematic writing instrument is desired.
Everyday Home Use
For everyday home use, the pen is applicable for journaling, casual drawing, planning, or any writing task where a fine line is preferred. The waterproof nature of the ink makes it suitable for entries that may be exposed to moisture, such as in sketchbooks or labels. It functions as a general-purpose pen with a specialised point for those who appreciate detailed work.
