How to use

Unscrew or disassemble the pen body according to the model’s standard procedure, remove the depleted refill and insert the replacement refill until it seats firmly. Reassemble the pen and verify that the tip extends and retracts (if applicable) and that ink flows by testing on a scrap of paper. If the refill does not fit smoothly, check orientation and seating; do not force components to avoid damage to the pen body.

Usage recommendations

Store spare refills capped or in original packaging away from direct sunlight and extreme temperatures to preserve ink consistency. For optimal results, use on standard paper and avoid pressing excessively to reduce skipping and prolong refill life.
