How to use

Uncap a fineliner and test the line on scrap paper to confirm ink flow and line width. Use steady pressure for consistent thin lines; adjust angle slightly to vary stroke width where needed. For technical drawing, work with a ruler or template to maintain straight lines. Replace the cap after use to prevent the pen from drying out and store the set horizontally or upright in a case to protect the tips.

Usage recommendations

For best results, combine the uni-ball The Tube Finerliner with suitable paper (medium to smooth surface) to reduce feathering and ensure crisp lines. Avoid prolonged uncapped exposure and keep away from extreme heat or direct sunlight to preserve ink quality.
