Francisco Arguelles Quisumbing, a chemist invented an indelible ink, which cleans the pen as it writes. It dries quickly on paper but remains liquid inside the pen.
He called the ink Quink short for Quisumbing Ink. He established Quisumbing Ink products, Co. in 1923 and supplied the government with this ink.
Parker Company bought the rights to the ink with Dr Quisumbing’s stipulation that the trademark “Quink” would be retained. Since then, Quink has become a popular product in many countries all over the world.
