Post-it® Transparent Notes are ideal for use in books, files, crafting projects and more-anywhere you need to make notes on items but easily see underneath. They're particularly useful for textbooks and manuals. Rather than just highlight an important passage, highlight it and note any important information, too! Alternatively, use these notes to color-code files or to trace images and patterns. Like all Post-it® products, these notes feature a unique adhesive that's designed specifically for paper-it sticks securely and always removes cleanly.
