The O Knock Rollerball Pen features OHTO's signature ceramic rollerball tip that ensures a smooth writing experience.
It has a handy function that will protect your pocket or notebook from accidental ink stains - as soon as you pull the clip away from the pen body to attach it to your pocket or notebook, the pen tip is automatically retracted.
The bottom half of this rollerball pen is made of brass which gives it a nice weight for writing, while the rest of the pen is made of plastic. It comes with black ink and is refillable with the OHTO Rollerball Pen Refill Medium.
OHTO was established in Tokyo, Japan in 1929 and began manufacturing high quality dyes & inks. The company has a long history of ink manufacturing as the founder of OHTO, Nakata Tozaburo, worked for the ministry of finance and invented a special ink for Japanese banknotes. Mr. Nakata went on to develop the first ballpoint pen manufactured in Japan in 1949. After the success of their 'Auto-Sharp' ballpoint pen, OHTO went on to design and manufacture the world's first rollerball pen in 1964.
The OHTO range now includes the original ballpoint and rollerball pens, as well as a range of writing instruments that suit your every need, from mechanical pencils to graphic liner pens, plus ceramic rollerballs, fountain pens and multi-function pens. OHTO continue to expand on their almost 100-year history of ink & writing instrument production by designing and developing new innovative products.
