A Prime Line® Exclusive!** PU magnetic bookmark. This clever bookmark sandwiches between your book cover and a few pages without bulk or damage. A slim tab keeps your page marked with precision, while a built-in side pen loop ensures your pen or pencil is always close at hand. Pen loop fits most standard pens; smaller pens can be secured by clipping over the loop. Magnets help secure the bookmark in place, so you never have to worry.
