Uni-ball One Gel Blue Pen Refill - 0.38 & 0.5 mm

• Enjoy vibrant, easy-to-read notes with the Uni-ball One gel pen. Its ink is specially formulated with large pigment particles that stay on the surface of the paper instead of getting absorbed into it.
• Since the ink isn't getting washed out by the paper, dark inks look darker, and bright inks look brighter. The ink is fast drying and bleed resistant too, so your notes will always be crisp and free of smudges.

Features:

• Vibrant, pigment-based ink that is fast drying and bleed resistant.
• Comfortable plastic barrel with a low center of gravity.
• Wire clip that opens wide for attaching the pen to a notebook or textbook.
