Irish designed, these Book-Ears are easy to use and perfect for keeping notes without spoiling your books. They have a magnetic strip that sits your Book Ear on the corner of your page and holds it in place. Folded down corners of a page are often referred to as 'dog ears', and are mostly frowned upon by readers, especially those who try to preserve the book in its original state. Book-Ears allow you to preserve each page while making notes on your reference pages. Perfect to use as bookmarks and ideal for study notes. No more dog eared pages and most importantly your books are maintained in their original condition.
