Double line outline pen 12 colour set with adjustable 1mm-2mm line width for creative projects

This double line outline pen set offers a specialised marking solution through its unique twin-nib design that creates parallel lines in a single stroke. Measuring 13cm in length with a metal body construction, each pen provides substantial weight for controlled application across various creative and practical tasks. The set includes 12 different coloured pens, all utilising water-based environmental protection ink that works effectively on paper surfaces. With an adjustable line width range between 1mm and 2mm, these pens accommodate different marking requirements from detailed artwork to bold signage.
Features and Construction

The double line outline pen combines functional design elements that support consistent marking performance across multiple applications. The metal body construction contributes to the pen's overall balance and handling characteristics, while the plastic pen tips are designed for immediate use without breaking in.
Material and Build
The pen's metal body provides structural integrity and sufficient weight for steady control during use. This construction contrasts with lighter plastic-bodied alternatives, offering a more substantial feel in hand. The plastic pen tips are manufactured to precise specifications to ensure consistent ink flow and line definition. The water-based environmental protection ink formulation represents a practical choice for paper-based projects, reducing specialist handling requirements compared to solvent-based alternatives.
Size and Practical Fit
With a standard 13cm length, these pens fit comfortably in hand while providing adequate ink reservoir capacity for extended marking sessions. The dimensions make them suitable for storage in standard pen cases, drawers, or creative tool organisers. The compact size facilitates portability for artists, teachers, or office workers who require reliable marking tools across different locations. The 12-pen configuration offers colour variety without excessive bulk, making it a space-efficient addition to any creative workspace.
Uses and Placement

The double line outline pen set serves multiple applications across creative, educational, and professional environments. Its distinctive parallel line capability distinguishes it from standard single-line markers, opening possibilities for decorative effects and functional marking that would otherwise require multiple tools.
Event or Professional Use
For event planning or professional settings, these pens excel at creating consistent parallel lines for signage, directional markers, or presentation materials. The adjustable 1mm-2mm line width allows customization for different visibility requirements, from subtle guidelines to prominent border elements. The water-based ink works effectively on most paper surfaces commonly used in professional environments, including card stock for name badges, poster board for displays, and standard paper for handouts. The 12-colour range provides flexibility for colour-coding systems or brand colour matching.
Everyday Home Use
In home settings, these pens support various creative projects including personalised greeting card making, decorative poster creation, and home organisation systems. The double line feature simplifies tasks like creating bordered journal pages, making decorative borders on craft projects, or adding parallel emphasis lines to notes and planners. Parents and educators find particular value in the consistent line creation for teaching writing skills, creating worksheets, or assisting with art projects where uniform spacing matters. The environmental protection ink formulation reduces concerns about indoor use around children or pets.
Benefits and Buying Value

The double line outline pen set delivers practical advantages through its specialised design and comprehensive colour selection. By combining multiple functions in a single tool, it reduces the need for separate rulers or multiple pens to achieve parallel line effects.
Reuse and Low Maintenance
These pens require minimal maintenance beyond standard pen care practices. The plastic tips don't require special cleaning or conditioning, and the water-based ink formulation means accidental marks on skin or surfaces generally clean easily with water. The metal body construction contributes to durability under normal use conditions, supporting reuse across multiple projects. When stored properly with caps secured, the pens maintain ink flow consistency for repeated use over time. The environmental protection formulation reduces disposal concerns compared to solvent-based alternatives.
Why Choose This Product
This double line outline pen set stands out for its combination of specialised functionality and practical design elements. The twin-nib construction addresses a specific marking need that standard pens cannot fulfil, while the adjustable line width provides versatility within that specialised function. The 12-colour configuration offers comprehensive coverage for most creative or organisational needs without requiring supplemental purchases. The metal body construction represents a practical choice for users who prefer more substantial tools over lightweight plastic alternatives. Together, these elements create a marking solution that balances specialised capability with everyday usability across multiple contexts.
