Supplied in a convenient box of 12, this pack ensures you have a ready supply of reliable pens for the office, classroom, or home study.

Features and Construction

This pen is built for straightforward, functional use with features focused on reliable performance in common writing scenarios.
Material and Build
The Deli A540 features a plastic pen barrel, making it lightweight and comfortable for extended writing sessions. It uses a ball-type ink delivery system paired with an oily ink refill in black. This combination is designed to provide a smooth, consistent flow onto the page, reducing the chance of skips or blobs. The pen employs a simple cap closure mechanism to protect the needle tube point when not in use.
Size and Practical Fit
The key specification is its 0.38mm writing thickness, which produces a fine line suitable for detailed work and neat handwriting. The product is specified for a writing length between 300 and 500 metres, giving a tangible measure of its ink capacity. The pens are supplied in a boxed pack of 12 identical units, a quantity suited for shared office spaces, student supplies, or as a personal stock to avoid running out.
Uses and Placement

The pen's design and specifications make it applicable for a range of standard writing environments and users.
Event or Professional Use
In office settings, the fine 0.38mm line is well-suited for completing forms, annotating documents, and writing in logbooks where space may be limited and clarity is paramount. The black, permanent oily ink ensures written records are legible and durable. A box of 12 pens can serve a small team or be kept in a central supply area for general use.
Everyday Home Use
For students, particularly middle school students, and for general home administration, these pens provide a reliable tool for homework, journaling, planning, and list-making. The fine point allows for writing in margins and compact notebooks. Having multiple pens in one purchase reduces the frequency of shopping trips for stationery essentials.
Benefits and Buying Value

The value of this product lies in its specific functional attributes and the convenience of the multi-pack format.
Reuse and Low Maintenance
Each pen is a single-use item designed for its full ink capacity. The low-maintenance design requires no refilling or complex mechanisms; you simply use the pen until its specified ink length is exhausted. The cap closure helps prevent drying if the pen is left uncapped briefly, supporting reliable performance throughout its use.
Why Choose This Product
Choosing the Deli A540 set is a decision based on specific, measurable needs: a requirement for a fine 0.38mm writing line, a preference for black oily ink, and the practicality of buying in a multi-pack. It provides a defined writing length and a straightforward design without specialised features, making it a cost-effective and functional choice for bulk, everyday writing tasks where precision and availability are the primary concerns.
