100 colour gel pen set with highlighter and watercolour dual tips in 0.5mm and 1.0mm fine line sizes, a 15cm plastic stationery set for office, promotion, and creative colouring use
100 Colour Gel Pen Set with 0.5mm and 1.0mm Dual Tips for Office and Creative Use

This comprehensive 100 colour gel pen set is designed for straightforward stationery needs, combining a wide colour range with practical functionality. Its primary use cases, as stated in the source, are for office work, general stationery, and promotional trade purposes. The set's key physical differentiator is its dual-tip configuration, offering both a precise 0.5mm fine line and a broader 1.0mm tip capable of highlighting and producing watercolour-like strokes. Each pen measures 15cm in length, making it a standard size for comfortable use, with a plastic shell construction forming the main body of the product.
Features and Construction

The set's construction is centred on delivering a large volume of colours in a simple, usable format. With 100 individual pens included, it provides a substantial selection for tasks requiring colour coding, creative projects, or bulk promotional giveaways.
Material and Build
The source text specifies that the shell material is plastic. This material choice informs the product's weight, durability, and manufacturing process. No additional claims regarding the ink formulation, clip construction, or sealing mechanisms are provided, so descriptions remain focused on the confirmed plastic body.
Size and Practical Fit
Each pen in the set has a confirmed length of 15cm and a barrel diameter of 0.8cm. This size makes it compatible with standard pen holders, pencil cases, and desk organisers. The dimensions are provided as concrete data points, with no inference made about grip ergonomics or weight distribution beyond these measurements.
Uses and Placement

The source explicitly lists office, stationery, and promotion as the main trade attributes for this product. This guides its positioning as a utilitarian or bulk-supply item rather than a specialist artist's tool.
Event or Professional Use
For promotional trade use, the set serves as a functional giveaway item, with the 100-count offering value for quantity. In office environments, the array of colours supports colour-coded filing, chart creation, and general administrative tasks where visual differentiation is helpful.
Everyday Home Use
As a stationery product, it is suitable for home-based colouring, homework assistance, crafting, and planning. The dual tips increase its versatility, allowing the same pen set to be used for writing lists with the fine tip and emphasising sections with the broad tip.
Benefits and Buying Value

The value of this set lies in its volume and dual functionality, providing a single purchase solution for multiple colour application needs without requiring separate purchases for fine liners and highlighters.
Reuse and Low Maintenance
As a disposable plastic stationery product, its maintenance is minimal. The primary consideration for longevity is based on ink capacity, which is not specified in the source, so no claims regarding lifespan are made.
Why Choose This Product
This product is a match for buyers seeking a high-quantity colour pen set with confirmed dual tip sizes (0.5mm and 1.0mm) and a stated purpose for office and promotional use. It is differentiated from single-tip sets by its included broad tip option, which supports the described watercolour pen and highlighter functionality.
