Ballpoint refill PENTEL EnerGel BL407 blue ink light blue barrel

PENTEL EnerGel BL407 is a ballpoint refill designed for pens compatible with the BL407 series. The refill contains blue ink formulated for smooth writing and rapid drying, delivering consistent lines and reliable ink flow for everyday tasks. The cartridge is housed in a light-blue barrel that makes identification easy and fits pens that accept BL407-type refills.

Its light-blue barrel improves visibility in storage and helps distinguish ink colour at a glance.
