How to use

Remove the cap or retract the tip as applicable and begin writing with light, even pressure. Allow a short moment for the rapid-drying gel ink to set on the paper before touching or stacking sheets to avoid transfer. When ink flow diminishes, replace with a compatible EnerGel refill by unscrewing or sliding open the barrel according to the pen’s construction, then insert the refill and reassemble.

Usage recommendations

For best results use on standard office or study paper and maintain a moderate writing speed to allow the quick-drying gel to perform optimally. Store the pen capped or retracted when not in use to prevent tip drying. Replace with manufacturer-recommended gel refills to preserve consistent ink flow and writing quality.
