How to use

Remove the pen cap or retract the tip, depending on the model, and write with light to moderate pressure to obtain a consistent ink flow from the 0.7 mm point.

Reassemble the pen and test on scrap paper before regular use.

Usage recommendations

Store the pen horizontally or with the tip up when not in use to reduce the risk of ink leakage; avoid exposing the pen to extreme temperatures. Use genuine or compatible 0.7 mm ballpoint refills to maintain writing quality and prevent damage to the feed mechanism.
