Onyx pen features

The uni-ball Onyx pen provides the feel of a luxury pen without the high cost. It has a sleek, straight design that feels comfortable in the hand, and  the metal point moves smoothly over the page to prevent skips when writing. The cap fits snugly over the tip to keep the ink from drying out. Onyx pens come in black, blue, and red for professional writing or editing. 

Benefits of the rollerball in uni-ball Onyx pens

Uni-ball Onyx rollerball pens are similar to ballpoint pens in that they use a tiny metal ball at the tip that rolls over the paper, releasing the ink inside the reservoir. The biggest difference between most rollerball pens and Onyx rollerball pens is Onyx uses liquid ink. Some benefits include:

• Consistent writing that doesn’t skip since the ink flows freely
• Handles like a fountain pen but reduces the mess from ink blobs
• Less pressure required to release ink to reduce hand pain
• Writes smoothly across the page for fast writing
• Produces dark, vivid lines with high readability
• Round barrel design for comfort
• Pocket clip for convenience

Uni-ball Onyx point styles

The Onyx has two point styles to choose from that are both small. The uni-ball Onyx micro pen is the smallest, with a point tip of .5 mm. The fine point pen option is .7 mm. The size of the point also determines the average size of the line when drawn. Since the lines are so small, the dark, liquid ink still helps the words stand out, so documents are easy to read. Uni-ball Onyx rollerball pens also reduce the risk of bleed through, which is when ink is visible from the back of the page. The pen is designed for small, sleek writing that can fill up a page. Writers with small handwriting will benefit from these point sizes.
