How to use

Remove the cap or extend the tip according to the pen's mechanism and begin writing. Apply normal writing pressure; the EnerGel ink is formulated for smooth flow without requiring extra force. Allow a brief moment for the ink to dry on the paper to avoid smudging, especially on glossy or coated surfaces. Store the pen capped or retracted when not in use to preserve ink quality and prevent drying.

Usage recommendations

For best results, use on ordinary paper and avoid excessive pressure or scratching motions. If you frequently switch between paper types, test on a small area to gauge drying time. Keep the pen capped when idle and store horizontally or tip-up to maintain optimal ink flow.
