Question

When were alcohol-based markers like these invented?

Answer 1

Alcohol-based markers, often referred to as permanent markers, were developed in the 1950s. The first permanent marker was introduced by the Sanford Ink Company in 1962, under the name "Sharpie." These markers use an alcohol-based ink that dries quickly and is resistant to water, making them ideal for various surfaces. Over the years, the design and formulation of alcohol-based markers have evolved, leading to a variety of types and colors available today.
