Mark+ series fibre-tip highlighter marker pens in six colours including grey pink and grey blue, measuring 131mm long with 15mm barrel diameter for students from primary school to university, non-erasable ink for permanent marking and annotation tasks
Mark+ Series Fibre-Tip Highlighter Marker Pens with 131mm Length and Six Colour Options

The Mark+ series presents a practical fibre-tip highlighter marker designed specifically for educational environments, serving students across multiple age groups from toddlers through to university level. With a substantial 131mm length and 15mm barrel diameter, these markers offer a comfortable grip suitable for extended highlighting sessions during study, revision, and document organisation. The non-erasable ink formulation provides permanent markings that won't fade or rub away accidentally, making them particularly useful for creating study guides, annotating important texts, or colour-coding materials that need to remain clearly marked over time. Six distinct colour variations allow for systematic organisation, with the unique Grey Pink and Grey Blue options providing subtle alternatives to traditional highlighter shades.
Features and Construction

These markers combine straightforward functionality with the practical requirements of educational settings, balancing size, ink performance, and colour variety in a single writing instrument.
Material and Build
The Mark+ markers utilise a fibre pen tip construction that delivers consistent ink flow without the skipping or uneven application sometimes experienced with cheaper highlighting products. While specific details about the barrel and cap materials aren't provided, the 15mm diameter suggests a substantial barrel designed for comfortable handling during extended use. The non-erasable ink formulation creates permanent marks that withstand handling and time, contrasting with erasable highlighters that might smudge or fade. This permanent quality makes them particularly suitable for important documents, textbooks, or study materials where markings need to remain legible throughout an academic term or year.
Size and Practical Fit
Measuring 131mm in total length, these markers fall within the standard range for comfortable highlighting instruments, neither too short to grip comfortably nor excessively long for storage in pencil cases or desk organisers. The 15mm barrel diameter provides sufficient girth for secure handling by users of different ages, from younger primary school students developing writing skills to university students requiring precision highlighting of dense academic texts. This balanced sizing accommodates the varied hand sizes across the stated user groups while maintaining a professional appearance appropriate for classroom, library, or home study environments.
Uses and Placement

The Mark+ markers address specific needs across educational contexts, from early learning environments to higher education settings where systematic study methods are essential.
Event or Professional Use
While primarily designed for educational purposes, these markers could serve in office environments for document coding, filing systems, or presentation preparation where permanent colour coding is beneficial. The non-erasable quality ensures important markings remain visible during meetings, audits, or collaborative projects. The six-colour range, including the distinctive Grey Pink and Grey Blue options, allows for sophisticated organisational systems beyond basic highlighting, enabling colour-based categorisation of projects, priority levels, or document types in professional settings that require clear, lasting visual differentiation.
Everyday Home Use
For home study sessions, these markers support systematic learning approaches from early childhood through teenage years. Toddlers can use them under supervision for basic colour recognition and early mark-making activities, while primary and secondary school students benefit from organised note-taking and textbook annotation. University students can employ the colour variety for complex subject coding in lecture notes, research materials, and revision guides. The permanent ink ensures study systems remain intact throughout revision periods, and the comfortable dimensions facilitate extended use during homework sessions, exam preparation, or independent research projects conducted at home.
Benefits and Buying Value

These markers deliver practical advantages through their combination of permanent ink, varied colour selection, and ergonomic design tailored to educational requirements.
Reuse and Low Maintenance
The fibre-tip construction typically offers reliable performance over the marker's lifespan, with the cap helping to prevent premature drying between uses. The non-erasable ink formulation means markings remain effective for reference purposes long after application, supporting study systems that build cumulatively over academic terms. While specific longevity data isn't provided, the permanent quality suggests the marked materials retain their organisational value rather than requiring re-highlighting as might occur with less durable options. This reduces time spent redoing colour coding and maintains consistent reference systems throughout extended projects or courses.
Why Choose This Product
Selecting the Mark+ series markers makes practical sense for anyone requiring reliable highlighting across educational stages. The specific 131mm length and 15mm barrel create a comfortable writing instrument suitable for varied hand sizes, while the six-colour range including unique grey-toned options supports sophisticated organisational systems. The non-erasable ink provides certainty that important markings won't disappear accidentally, which is particularly valuable for study materials that might be handled frequently or stored for future reference. By addressing needs from toddler activities through university-level work with a single product type, these markers offer versatile functionality without requiring multiple specialised products for different age groups or educational purposes.
