The bookends are made of sturdy metal with advanced technology, which is strong enough to hold up your books neatly and upright. It is not easy to deform and bend. The surface is painted with the electrostatic spray that prolongs the book ends service life as well as prevents rust and scratches. Electrostatic spray-coated surface prolongs the service life of the book ends holder, and round edges make sure that your books and hand don't get any scratches or scuff marks. With 4 anti-slip foam pads on the bottom of each black bookend keeps books from sliding and allows you to move the book end but will not scratch your desk. They are also used as bookshelf dividers for separating different subjects and make it possible to leave a space without the books learning. The metal book ends with special tree-shaped designs, which add a subtle comfortable feeling to your desk or bookshelf. Decorative bookends are suitable for holding up your books to the end of open shelves/desks/bedside tables, help add an extra shelf on the flat space. The slim design will not occupy valuable space on your shelf or desk and will keep your book in order. Great for books, magazines, movies, DVDs, video games, and anything else you want to stand up for. It is a great gift for children and officers.
