Page Points - Levenger
These are the best page markers I've used. I buy them in copper. When I was in college I used these in my school books instead of using all the post-it notes (which, don't get me wrong, I use a lot, but these take up less space and point directly at what you need). Now, I use them in some of my better cookbooks. So far, I've only been able to find them online at Levenger. If you know of another place, please let me know.
