Stationery correctors: easily correct errors
When the corrector appeared in our stationery stores, everyone managed to appreciate its advantages - schoolchildren, students, office workers. Many still remember unsuccessful attempts to erase the pen mark in a school notebook with a blade or eraser, which most often hopelessly spoiled the page. The history of liquid corrector for paper began in 1951. American Bette Graham worked as a secretary, and like no one else knew the price of mistakes - if they appeared, she had to reprint the entire page on a typewriter. The idea came when Bette remembered how artists work. Having made a mistake, they do not wash off the paint, but apply a new layer on top. This was followed by long experiments with the composition of the corrector fluid and improving its properties. In the end, we got wonderful helpers in work and study, which we now use with pleasure.
