Ball Pen Ajnala(b) Amritsar

As early as the 19th century, attempts had been made to manufacture a pen with a rolling ball tip, but not until 1938 did the Hungarian brothers Georg and Ladislao Biro invent a practical ballpoint pen. Its success was based upon a viscous, oil-based ink. Early ballpoint pens did not write well; they tended to skip, and the slow-drying oil-based ink smudged easily. The ink was waterproof and almost unerasable; the pen could write on many kinds of surfaces and could be held in almost any position for writing, and the pressure required to feed the ink was ideal for making carbon copies.
