Ex-IDEO engineer, Alan Regalabrings us another great office product invention. The Bookmarker is: 1) pen, 2) flag dispenser, 3) bookmark & 4) book strap to keep your book closed. It was designed for people who take notes in notebooks, textbooks, journals, reading books etc). The advantage this product provides is instant access to important note-taking tools because the product is super thin and fits and stores inside your book. The product is completely refillable with standard size sticky flag & pen refills.
