15cm Multifunction Ballpoint Pen with Integrated Vernier Caliper for Students and Office Use

This product addresses a specific, practical need: combining everyday writing with basic measurement capabilities. It is a ballpoint pen with a 0.5mm tip, noted for providing smooth writing, that also incorporates a vernier caliper scale along its body. Designed for portability at 15cm long and made from ABS plastic, it is presented as suitable for student projects, general office tasks, and as a functional gift. Available in a choice of six body colours and two refill ink colours, it offers a straightforward, two-in-one tool without requiring separate items for simple drafting or measuring work.

Features and Construction

The core design integrates two common tools into a single, portable unit. The primary function is as a writing instrument, while the secondary function provides a basic measuring scale, eliminating the need to carry separate items for light tasks.

Material and Build

The pen is constructed from ABS plastic, a material chosen for its rigidity and lightweight properties, making it suitable for a handheld writing instrument. The construction involves moulding the plastic to form both the pen barrel and the integrated vernier caliper scale. The source text does not provide data on the specific grade of ABS or any performance claims regarding its durability or longevity.

Size and Practical Fit

With a total length of 15 centimetres, the pen is designed to be easily portable, fitting into pencil cases, shirt pockets, or bags. This compact size makes it convenient for students or office workers to carry. The vernier caliper function is built into this existing form factor, adding measurement utility without increasing the item's bulk or altering its primary shape as a pen.

Uses and Placement

The product is explicitly listed for several use cases, focusing on environments where simple measuring and note-taking intersect. Its dual role is its main selling point for these scenarios.

Event or Professional Use

In an office or light professional setting, this pen can be used for quick sketches, noting dimensions during discussions, or basic prototyping where approximate measurements are sufficient. It serves as a handy desktop tool for engineers, designers, or workshop staff who need to jot down notes and a quick measurement without fetching specialised tools. The source does not support claims for precision engineering or technical drafting.

Everyday Home and Student Use

For students, it is marketed as a practical tool for geometry, design technology, art projects, or science experiments at school or home. It allows a student to measure and record data with one item. As a gift for children, it offers an introduction to basic measuring tools combined with a familiar writing instrument. The 0.5mm tip is described as creating a good writing experience, suitable for everyday homework and note-taking.

Benefits and Buying Value

The value lies in convenience, reduced item count, and targeted functionality for specific user groups. It is a niche product that solves a clear, if simple, problem.

Reuse and Low Maintenance

The pen uses replaceable refills (available in black or blue), allowing the main body and caliper function to be reused. Maintenance involves simply changing the refill when the ink is depleted. The ABS plastic body can be wiped clean if needed. No complex care instructions are provided or required, aligning with its simple design.

Why Choose This Product

Choose this product if you need a single, portable tool for occasional basic measuring alongside regular writing. Its advantage is convenience for students, hobbyists, or office workers who perform light technical tasks. The choice of six body colours (orange, blue, red, green, black, silver) allows for personal preference or colour-coding. It is not a replacement for precision measuring instruments but serves as a practical, all-in-one tool for its stated uses.
