Refill for the 0.5mm ballpoint OHTO Days pen


Established in Tokyo in 1929, OHTO has been making innovations to both pens and inks ever since. When they made the first Made in Japan ballpoint pen in 1949 it used a chrome ball. Years of research led them to a resin polyamide ball and many years of experiments after that the ceramic roller pen was introduced. In 1963, they developed the world’s first water based ballpoint pen, fade resistant ink came, then waterproof ink, soft ink and Cera-Gel.
