Index Cards

Index cards are small, rectangular pieces of thick paper commonly used for writing, organizing, and studying information. Available in various sizes—most commonly 3″ x 5″—they are ideal for notes, flashcards, recipes, or presentations. Their sturdy cardstock construction makes them durable and easy to handle. Index cards come in plain, ruled, or grid formats, and are often color-coded for better organization. They are widely used by students, teachers, and professionals for efficient information recall and categorization. Convenient for both manual and digital filing systems, they can be stored in boxes or binders. Simple, portable, and highly effective for quick reference.
