fountain pen enthusiasts, Parker Quink is generally considered to be "safe fountain pen ink"; this means that it should not stain or clog fountain pens very easily. The use of fountain pens gradually decreased during the second half of the 20th century. Many collectors and enthusiasts continue to use the Parker 51 pen in the 21st century, with a limited edition of the model (available in two colors, "Vista Blue" and black) released by Parker in 2002. As part of the 2002 product revival, Parker promoted its quick-drying ink as the ideal accompaniment for the Parker 51.
