How to use

Remove the cap or retract the tip if applicable, then write using light, consistent pressure to maintain the smooth ink flow and avoid skipping. Replace the refill when ink runs low by unscrewing or opening the barrel according to the pen’s construction and inserting a compatible gel refill until it seats securely. Store the pen capped or retracted when not in use to prevent the tip from drying out.

Usage recommendations

For best results, use on standard office paper and avoid prolonged contact with glossy or heavily coated surfaces. If the line becomes faint, check refill seating and replace with a compatible gel refill. Keep capped or retracted when idle to preserve ink performance.
