Bookmarks are handy, slender tools designed to hold a reader's place in a book or other printed material. They are typically placed between pages to mark where the reader left off, allowing for easy and quick retrieval of the same spot. Bookmarks come in various designs and materials, and they can also serve as decorative accessories or promotional items. These simple but practical tools enhance the reading experience and make it convenient to pick up where you left off in your favorite book or literature.
