How to use
Remove the cap and hold the pen at a comfortable angle to the paper so the 0.5 mm tip makes consistent contact. Apply light, even pressure while writing; the gel ink is formulated to flow smoothly without requiring heavy pressing. Replace the cap after use to prevent the tip from drying out. For best results, use on standard paper and allow a few seconds for the ink to set before stacking or closing pages.
Usage recommendations
Store pens horizontally or with the tip down during prolonged storage to help maintain immediate ink flow. Avoid using on glossy, non-absorbent surfaces where gel ink may take longer to dry. For archival or official documents, perform a quick smear test on a spare sheet to confirm drying time under your specific conditions.
