Post-it Page Markers are ideal for temporarily marking pages in books and reference materials. Use them at the top of a page for a bright bookmark, in the text margin for making notes without marking on the pages themselves, or just to call attention to specific information. They hold securely and reposition easily. Can be written on. Won't tear or damage book pages. Ideal for color-coding materials by topic, reader, importance and many more ways. 50 sheets per pad.
