PILOT Hi-Tec C Coleto Refill, 0.5mm

While the 0.3mm and 0.4mm refills are beloved for their microscopic precision, the 0.5mm Coleto refill is the "power writer" of the family. It provides a slightly bolder, more saturated line that stands out on the page, making it the ideal choice for those who prioritize legibility and a buttery-smooth writing feel. If you find yourself writing at a fast pace or taking long-form notes, the 0.5mm offers the least resistance while maintaining that classic Hi-Tec C needle-point accuracy.

Integrated Key Features & Technical Specifications
Robust 0.5mm Needle Point: The precision-machined stainless steel needle tip is designed to be sturdy enough for heavy-handed writers while remaining fine enough for standard planners and journals. The tip design offers an unobstructed view of your paper, which is a hallmark of the Hi-Tec C series.

Vibrant Biopolymer Gel Ink: Each refill is loaded with Pilot’s high-performance biopolymer gel ink. This formula is engineered to be feather-resistant and incredibly vivid, ensuring your 0.5mm lines remain crisp and clear without the "globbing" often found in standard ballpoints.

Integrated Slide-Lever System: Every refill is an all-in-one unit featuring its own colored slide lever. When inserted into any Coleto body, this lever functions as the activation clicker and serves as an instant visual color indicator at the top of the pen.

Standardized 126mm Length: These refills are 126 mm long and are perfectly compatible with the entire range of Coleto barrels (2-slot, 3-slot, 4-slot, and 5-slot), allowing for infinite customization of your writing toolkit.

Fast-Drying Performance: Despite the slightly higher ink flow of the 0.5mm tip, the gel formula is designed to set quickly. This makes it a reliable choice for everyday tasks where you can’t afford to wait for ink to dry before closing your notebook.

Top-Loading Convenience: Designed for the modular Coleto system, these refills slide directly into the top of the pen body. You can swap colors or replace an empty refill in seconds without ever having to disassemble the barrel.
