Uni-ball Lakubo Ballpoint Pen, 1.4 mm Broad, Smooth Oil-Based, Bold Lines, Soft Grip, Ideal for School, Office, Priorities & Labels - Blue

Key features include a broad 1.4 mm line width for high visibility, smooth oil-based ink for effortless strokes, faster drying to reduce smearing, a soft cushioned grip for comfort, and a durable tip designed for frequent use.

The pen performs well on standard notebook paper, printer paper, and most office papers. The quick-drying oil-based ink helps minimize smearing on common writing surfaces, though very glossy or coated surfaces may show more texture.

Oil-based ink lays down smooth, even strokes with reduced writing effort and produces bold lines that remain legible over time. The ink also dries quickly to resist smearing during handling.

Yes, the 1.4 mm line width is ideal for checklists and labels where emphasis is important. If you need finer handwriting or detailed notes, you might prefer a 0.7–1.0 mm Lakubo variant.

The Lakubo SG100B features a soft cushioned grip that reduces hand fatigue and provides better control, especially when writing in long sessions or when you’re emphasizing items on a page.

Lakubo pens of this line are typically designed as reliable, long-lasting disposables rather than refillable cartridges. When the ink is exhausted, you would replace the pen.

Keep the cap on when not in use to prevent the nib from drying, store in a cool, dry place, and avoid dropping the pen to protect the tip. Regular use helps prevent ink from clogging in the nib.

The SG100B with 1.4 mm lines creates bolder strokes ideal for prominent checklists and labels, while the SG100A with 1.0 mm lines is finer and better for detailed writing. For more emphasis-free notes, SG100A may be preferred; for high-visibility elements, SG100B shines.

The Lakubo SG100B is designed for school and office use and is generally considered non-toxic for standard writing tasks. Avoid ingestion and keep out of reach of small children. It’s intended for writing, not as a toy.

Consider line width, ink type (oil-based for bold lines and smoothness), grip comfort, and durability of the tip. The 1.4 mm Lakubo offers bold lines with quick-drying oil ink, which is valuable for checklists and high-visibility notes. If you need finer writing, look at narrower Lakubo variants or other pen families on Fepy for a balance of ink feel and line width.
