Promising review: “These babies are pretty sturdy and they make putting notes in a book, planner, magazine, or whatever, a complete breeze. I really like the ease of these and if you are creative you can make these work for any project. I use them in my textbooks to summarize my notes on a chapter. I also have short-term memory loss after a car accident, and I like reading novels, but can’t remember things, so I use one of these as a bookmark, and take a few minutes to jot down key things from the book. I really, really, really like these and I am glad they exist.” —Delaney
