How to use

Uncap the pen and begin writing; apply light to moderate pressure to achieve consistent ink flow and thin lines. For cartridge replacement, follow the instructions printed on the product packaging: remove the barrel cap or unscrew the barrel as indicated, extract the spent cartridge, and insert a compatible replacement until it seats securely. Store the pen capped when not in use to prevent drying and to maintain tip performance.

Usage recommendations

Use on standard paper weights for best results; avoid porous or heavily textured surfaces that can cause feathering. If skipping occurs after long storage, recap the pen and gently depress the tip on scrap paper to reestablish ink flow.
