Margin Ultra Tabs offer a narrow body that fits within the margins of books, notebooks and printed documents without interfering with text. This makes indexing, flagging and referencing documents quick and easy. Durable tabs are writable on both sides. Adhesive body is clear so you can see text underneath. You can write on these smudge-free page tabs with most pens, pencils, markers and highlighters (Ink dry times may vary; tab may lift some inks). Repositionable tabs stick securely, but remove easily without leaving any residue or lifting ink. They are perfect for home, school or the office. Use these sticky pastel tabs as page flags or index tabs in cookbooks. Students, teachers and administrators will find it easy to highlight textbooks and notes without marking the pages. At the office, make quick and easy sticky notes in your planner and mark items in a report or presentation for referencing, follow-up or signatures. Tab colors include six each in blue, pink, purple and green.
