By making the black ink-drawing rod foldable, the overall length when in operation is more than 1 cm shorter than conventional mini converters, making it compatible with Kaweco Lilliput pens. Furthermore, once folded, it locks into place, preventing ink leakage as the drawing rod lowers. This converter is compatible with Splatoon, Dia 2, Student, Pakeo, Special, Kaweco Original, Classic Sport, Skyline Sport, Frosted Sport, Calligraphy Sport, Art Sport, AC Sport, Ice Sport, AL Sport, Brass Sport, Bronze Sport, Steel Sport, and Lilliput pens.
