ペン芯。 A comb groove formed by a large number of comb teeth arranged in parallel on the outer periphery, a slit-like ink groove vertically provided on the comb teeth across the comb groove, and an air exchange groove formed in the axial direction by the notches of the comb teeth. In a pen core equipped with a pen core, the air exchange groove is formed by cutting out one place on the circumferential surface of each comb tooth in the rear comb tooth group, and a single strip of the rear groove formed by cutting out one place on the circumference of each comb tooth in the front comb groove group. Formed with two notches on the surface,
A pen core for a writing instrument comprising two front grooves in the axial direction that diverge from the rear groove to allow ventilation to the front side.
