How to use

Ensure the pen barrel is a G1-type model and remove the empty refill following the barrel manufacturer’s instructions. Insert the PILOT BLS-G1 refill firmly until it seats in the tip section; secure any fastening mechanism if present. Test the pen on scrap paper to prime the gel ink and confirm smooth, even flow before resuming regular writing.

Usage recommendations

Store refills capped or upright at room temperature to prevent drying. If the ink flow slows, gently scribble on scrap paper to restore consistent delivery. Use the refill in compatible G1-style barrels to maintain tip alignment and ink feed performance.
