How to use

Remove the cap and hold the pen at a comfortable writing angle. Apply light, even pressure for fine, controlled lines; heavier pressure will not increase line width significantly but may shorten tip life. Store pens horizontally or with the tip down to maintain reliable ink flow and replace caps after use to prevent drying. For forms and signatures, allow a second for the ink to dry to avoid smudging on glossy surfaces.

Usage recommendations

Keep a few pens from the pack in different locations such as desk drawers, briefcases and backpacks to ensure a ready supply. Use on standard paper and avoid prolonged contact with wet surfaces. For archival or legal documents where pigment ink or permanence is required, verify ink suitability before use.
