## Long description

uni-ball UB EYE Design 0.4 mm in violet is a rollerball pen engineered for precise writing and detailed note-taking.

Key specifications
 Tip size: 0.4 mm (fine)
 Pen type: rollerball
 Ink color: violet
 Line characteristics: narrow, consistent lines
 Ink flow: smooth, low-skip formulation
How to use
Remove the cap and hold the pen at a comfortable angle for writing. Apply light, consistent pressure to allow the rollerball tip and ink feed to produce even lines; heavy pressure is unnecessary and may affect tip performance. Replace the cap after use to prevent drying and store the pen horizontally or tip-up for extended periods to maintain optimal ink flow.
Usage recommendations
For the best results, use the pen on standard, moderately smooth paper to preserve tip life and maintain clean lines. When producing detailed work, allow freshly written ink to dry briefly before stacking pages or closing notebooks.
