Uni Jetstream 4&1 Multifunction Ballpoint Pen MSXE5-1000, 0.7mm Oil-Based Inks (Black/Red/Blue/Green) & 0.5mm Mechanical Pencil, Slate Grey, MSXE510007.61

Exceptionally Smooth Writing: Ultra-low-friction Jetstream ink reduces drag by up to 40%, delivering a consistently smooth, satisfying writing experience at any speed or pressure. Crisp, Bold Lines: A refined blend of colorants and pigments creates ink with roughly twice the density of conventional formulations, producing clear, dark lines that stand out on any paper. Excellent Quick-Drying Performance: The advanced ink absorbs swiftly into the page and dries rapidly, minimizing smudging and helping keep your hands clean. Innovative Mechanism Prevents Ink Flow and Backflow: A spring tip paired with a twin-ball system supports smooth, low-viscosity ink while blocking leaks and backflow for consistent performance. Thoughtful Design and Functionality: With balanced construction, an elastomer grip, four ink colors (black, red, blue, green), and a built-in mechanical pencil, this compact and lightweight body brings five functions together in one.
