100 Colour Gel Pen Set with 0.5mm and 1.0mm Tips for Office and Art Use

This 100-piece colour gel pen set provides a comprehensive stationery solution for environments requiring a wide colour range and functional versatility. Each pen in the set is constructed with a plastic barrel measuring 15cm in length and 0.8cm in diameter, offering a standard size for comfortable handling. The inclusion of two distinct tip sizes—0.5mm and 1.0mm—allows users to switch between fine detailing for precise annotations and broader strokes for colouring or highlighting. Designed with office, educational, and promotional applications in mind, this multipack serves as a practical bulk supply for organised note-taking, creative art projects, or corporate giveaways, supplying all the colours needed in one convenient set.
Features and Construction

The set’s construction focuses on delivering reliable performance for everyday writing and colouring tasks. With 100 individual pens, users have access to a full spectrum of colours suitable for coding documents, illustrating, or adding visual interest to planners and journals.
Material and Build
The pens feature a plastic shell material, which creates a lightweight yet durable barrel resistant to cracking under normal use. This material choice ensures consistency across all 100 units and supports cost-effective production for bulk stationery sets. The plastic construction contributes to the pen’s overall balance and grip, making it suitable for extended writing sessions in office or study settings.
Size and Practical Fit
Each pen measures 15cm in length with a barrel diameter of 0.8cm, dimensions that align with standard pen sizes for easy storage in pencil cases, desk organisers, or promotional packaging. The 0.5mm and 1.0mm tip options cater to different applications: the finer 0.5mm tip is ideal for detailed diagrams, marginal notes, or intricate artwork, while the 1.0mm tip provides smoother, more visible lines for general writing, underlining, or bold colouring blocks.
Uses and Placement

This gel pen set is designed to fulfil multiple roles, from professional and academic tools to creative and promotional items. Its broad colour range and dual-tip functionality make it adaptable to various contexts where colour differentiation and writing clarity are important.
Event or Professional Use
In office or promotional environments, the set can be used for colour-coding files, creating presentation visuals, or as branded giveaways at trade shows and corporate events. The 100-piece quantity ensures there are enough pens for team distribution or client gifts, while the plastic barrel offers a sturdy, presentable appearance for business-related stationery.
Everyday Home Use
For home, school, or personal art projects, the pens support activities like journaling, sketching, homework assignments, and crafting. The watercolour-like gel ink can blend for artistic effects, and the variety of colours encourages creative exploration in scrapbooks, bullet journals, or children’s artwork without needing multiple separate purchases.
Benefits and Buying Value

Choosing this 100-colour gel pen set brings practical advantages centred on convenience, versatility, and cost-effective bulk supply. The set eliminates the need to buy individual pens, providing a complete colour palette ready for immediate use.
Reuse and Low Maintenance
Each pen is a self-contained unit, allowing for simple replacement if one colour runs out while others remain usable. The plastic barrels are resilient enough for repeated handling, and the gel ink formulation typically offers consistent flow without frequent skipping, reducing frustration during use. No specialised maintenance is required beyond standard pen care, such as capping when not in use.
Why Choose This Product
This set stands out for its combination of quantity, dual-tip options, and application range. Unlike smaller packs, it offers an extensive colour selection that covers both everyday and niche shades, while the 0.5mm and 1.0mm tips provide adaptability for different tasks. The 15cm size ensures compatibility with common storage solutions, and the plastic build maintains a practical balance of durability and affordability, making it a sensible choice for users seeking a comprehensive, multipurpose stationery set.
