highlighter

A highlighter is an indispensable stationery tool used primarily for marking and emphasizing key sections of text within documents, books, notes, or worksheets. It generally features a barrel-shaped body made of durable plastic or other lightweight materials, which houses a fibrous ink reservoir. The ink itself is usually brightly colored and fluorescent, available in a variety of shades such as neon yellow (the most common), bright pink, vivid green, deep orange, and electric blue. This range of colors allows users to categorize information by color, aiding in studying or reviewing material. The tip of a highlighter is chisel-shaped, allowing the user to make broad strokes for covering entire lines or smaller, precise marks when underlining or focusing on smaller text. The ink’s formulation is designed to be semi-transparent, so the underlying text remains fully readable even when highlighted.

Highlighters are commonly employed in educational settings, such as schools and universities, where students use them to review textbooks or class notes, helping to absorb information more effectively by organizing content visually. They are also used in professional environments, especially in tasks that involve document review, proofreading, or project management, where critical points need to be quickly located. Over time, highlighters have evolved into various forms, including retractable models, refillable versions, and even eco-friendly options made from recycled materials. Some highlighters are designed to be erasable, allowing users to remove or adjust markings without damaging the original text.
