P.S.

OHTO manufactured world’s first rollerball pen in 1963, and world’s first pencil shaped ballpoint pen in 1949; this is the first MADE IN JAPAN ballpoint pen.

OHTO 為日本以至全世界製筆的先驅品牌－世界第一支走珠筆 (1963) 及日本自產的第一支原子筆 (1949) 均係出自OHTO之手！

Nowadays, OHTO produces not only ballpoint pen, but also professional drafting pencil. Especially Super Promecha Series, user can customise everything from the length of lead dispensed with each click to the length of the guide pipe. By twisting the grip, you can adjust the lead sleeve length from 0 mm to 4 mm. And by twisting the rotating component inside the window, you can adjust the length of lead extended with each click from 0.2 mm to 2 mm.
