Uni-ball Signo Impact Gel Pen, 1.0 mm Broad, Waterproof Pigment Ink, Quick Dry, Smudge-Free, Ideal for School & Office Use - Blue

Bold 1.0 mm tip, pigment gel ink for saturated blue color, quick-drying and smudge-free performance, uni Super Ink protection, a comfortable grip, and a durable stainless-steel tip that maintains shape for consistent lines from start to finish.

The 1.0 mm tip produces thicker, more pronounced strokes that stand out on forms and notes, making headings, labels, and important text easier to spot than finer 0.7 mm options.

uni Super Ink is a pigment-based ink that resists water, fading, and tampering. This helps ensure your writing remains legible and secure over time, which is useful for important documents and long-term notes.

Ideal for signing forms, labeling folders and notebooks, writing class notes, and outlining exams or presentations where bold, legible text is beneficial.

Always cap the pen when not in use, store on paper or in a pen sleeve, and avoid extreme heat. If the ink starts to feel dry, a gentle shake or a brief write to prime the tip can help restart smooth flow.

The pen uses standard, non-toxic ink suitable for everyday writing and classroom use. As with all writing instruments, keep small parts away from young children and supervise use in younger ages.

Yes. The pigment gel ink is designed for smooth operation on standard paper types used in schools and offices, making it suitable for notebooks, planners, labels, and handwritten forms. For glossy or coated surfaces, test a small area first to confirm how the ink sits.

Uncap, press the tip to the paper with light initial pressure to establish a smooth line, then write with a steady, moderate pace. Cap again after use to minimize drying, and store the pen in a cool, dry place.
