First introduced in 1972, the Ball Pentel B100 is a long-standing classic of Japanese stationery. Its distinctive green body houses a 0.6 mm resin tip, designed to produce a smooth and consistent flow of water-based ink.
Simple, lightweight and functional, the B100 has remained remarkably unchanged over the decades. Its instantly recognisable form reflects Pentel’s practical approach to everyday writing tools — reliable, economical and made to be used.
