Uni-ball Micro Deluxe Rollerball Pen, 0.5 mm, Waterproof Pigment, Smooth Uni-Flow, Ideal for Everyday Writing - Red

It uses a 0.5 mm rollerball tip with a water-resistant pigment ink for clear, consistent lines on a variety of papers.

Uni-Flow regulates ink output to deliver a steady, even line from the first stroke to the last, reducing skips and inconsistent writing.

The pigment ink is water-resistant, helping resist smears when exposed to light moisture or handling.

The ink is quick-drying, which helps minimize smears on typical writing surfaces and reduces smudging when you review notes shortly after writing.

Best suited for journals, ledgers, forms, checklists, and annotations where clean, legible lines are important.

Write with a comfortable, moderate pressure to maintain a consistent line. Keep the pen capped when not in use and store it in a cool, dry place to preserve the ink quality.
