I love highlighting things. I don't know why I just do. My favorite(of the moment it changes all the time) is BIC Bright Liner Fluorescent Highlighters! There awesome! Don't highlight gel pens or pencils though because it smudges them really bad.
I really like how these BIC Mechanical Pencils write. There #2 so there perfect for tests. Plus they come in multiple colors!
I love these pens! Papermate Eagle in Medium are the best! They write awesome! And they don't smudge with highlighters!
