What is the Artline Supreme antimicrobial fineliner?

It is the black 0.4mm version of Artline's Supreme fineliner range, catalogued as antimicrobial and supplied as a box of 12 pens. The fibre nib lays down a consistent 0.4mm line, and the water-based ink is formulated so it won't bleed through the paper. Each pen measures 165mm long with a slim plastic barrel.

Why an antimicrobial fineliner matters for shared workplaces

Pens are among the most-handled items on any desk. An antimicrobial-treated barrel is designed to resist microbial growth on the pen's surface, which is a sensible feature wherever a pen passes between many hands.

For busy offices, that means a reception or shared-desk pen that stands up to constant use. For schools, it suits classroom pen pots and sign-in sheets handled by dozens of students a day. For hospitals and clinics, it fits ward stations, handover desks and admin areas where the same pen is picked up shift after shift. The pen is a general-purpose writing instrument, not a medical device, so treat it as everyday stationery rather than clinical equipment.

Key features and specifications

Every pen writes for over 1,300 metres of line, so a single box of 12 covers a long stretch of note-taking before replacement. The 0.4mm fibre nib gives a fine, precise stroke that suits small boxes on forms and tight margins.

The water-based ink resists bleed-through, making the pen practical for double-sided notes and thinner office paper. A curved pinch grip supports the fingers for comfortable writing over longer sessions, which helps during long note-taking, marking or charting stretches. The slim 165mm barrel and light 10g weight make the pen easy to slip into a shirt pocket, pencil case or lanyard pouch. The pens are RoHS compliant and xylene free, and they are made by Artline, a brand of the Japanese company Shachihata, which holds ISO certification for both its quality assurance and environmental management systems.

How it works across offices, classrooms and wards

In the office, the 0.4mm line is ideal for filling in expense forms, annotating printouts and keeping a legible desk diary without ink soaking through the page.

In the classroom, the fine nib and comfortable grip help students with neat handwriting, diagrams and labelling in exercise books, while the box of 12 keeps a whole group supplied.

On the ward, staff can use the fineliner for handover sheets, ward paperwork, observation charts and admin forms where a clean, non-bleeding line keeps records easy to read. Always follow your own facility's guidance on pens and record-keeping.

Tips for getting the most from your fineliners

Store the pens flat or nib-down and replace the cap firmly after use to keep the fibre tip from drying out. For double-sided printing and forms, the water-based ink is a better fit than a heavy solvent marker, because it dries flat and won't strike through. If you want a splash of colour for coding or highlighting alongside your black pens, the wider fineliners range covers other options.

0.4mm or a bolder tip: which should you choose?

The 0.4mm nib is a fine-line width, best for detailed work: form-filling, neat handwriting, margin notes and small diagrams. If you regularly write in tight spaces or complete printed forms, the fine line keeps everything legible.

Choose a bolder fineliner or a broader marker instead when you need a heavier line for signage, headings or bold labelling. Many offices, classrooms and wards keep both on hand: a box of fine 0.4mm pens for everyday writing and a chunkier marker for anything that needs to be read from across the room.
