The rollerball pen was first launched on the Japanese market in the latter half of the 1960's.
The rollerball pen is unmatched for its smooth writing action and densely colored writing line. It writes as clearly as a fountain pen, but with little maintenance. Anyone can write with a rollerball pen. Because it writes with a ball, not a nib, it does not need to be broken in like a fountain pen and it will not wear down like a felt tip. It can be held at virtually any angle and its ink will still be fed to the point.
As a drawing instrument, a rollerball pen can be used for most types of drawing including superfine lines. It does not blob and it produces a line which, because of its density and definition, photocopies particularly well. A rollerball ink is slower to dry on less-absorbent surfaces such as glossy paper or printed matter such as magazines than a ballpoint pen.
The quality of the writing ink is not only determined by the pen. It will also be affected by individual writing pressure, the softness of the paper used and to a lesser extent, whether prevailing environmental conditions are dusty, dry or humid.
