Key specifications

How to use

Remove the cap and hold the pen at a comfortable angle to apply even pressure while writing. Use steady, light strokes for the finest lines and increase pressure slightly if a slightly thicker line is required. Store pens horizontally or with the tip down for immediate use and to maintain consistent ink flow. Replace caps after use to prevent drying.

Usage recommendations

For best results, use on standard office or school paper; avoid heavily textured or coated papers that can affect line quality. Allow fresh ink markings a moment to dry before stacking pages to reduce the risk of smudging. Keep a spare pen from the pack for backup during prolonged tasks.
