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: The Jetstream ink with extremely low friction reduces air resistance by up to 40% and ensures a consistently smooth, satisfying writing experience at every speed and pressure. Clear, bold lines: A sophisticated blend of dyes and pigments creates ink with about twice the density of conventional formulations, producing clear, dark lines that stand out on any paper. Exceptional quick-drying performance: The advanced ink absorbs into the page swiftly and dries quickly, minimizing smearing and keeping your hands clean. Innovative mechanism prevents ink flow and backflow: A spring tip paired with a dual ball system supports smooth, low-viscosity ink while simultaneously blocking leaks and backflow for consistent performance. Thoughtful design and functionality: With a balanced construction, an elastomer grip, four ink colors (black, red, blue, green) and a built-in mechanical pencil, this compact and lightweight body combines five functions in one.
