A red pen is more than just a writing instrument—it’s a symbol of correction, attention, and authority. Teachers, editors, and professionals often use red pens to highlight errors, emphasize important notes, or mark changes in documents.
Historically, red ink stood out against black or blue text, making it ideal for proofreading and grading. While digital tools are now common, the red pen remains a trusted analog companion in many workflows.
Whether you're correcting homework, editing a manuscript, or simply doodling with flair—this is a red pen: bold, clear, and unmistakable.
