Blue extra fine point rolling ball pen

These rolling ball pens feature a liquid ink formula that provides smooth, consistent strokes. The patented needle point technology ensures precise writing, while the ringed ink feeder delivers an even flow of ink. A visible ink supply allows you to monitor ink levels easily. The pens have a 0.5mm extra fine tungsten carbide tip, suitable for detailed writing. Available in various colors, they are ideal for emphasizing, organizing, and color-coding information. Designed for reliable performance, these pens can write through multiple layers of copies. The ink flow remains steady from start to finish thanks to the concentric ring ink feeder system. They offer a larger ink capacity for extended use and are nonrefillable.
