Just slip the metal prongs into the top of the book (as shown) to show the page you want to keep open. And it will stay open. If there is a page you want to turn, avoid clipping that page so you can flip that page. So simple. The original, the best on the market! Avoid those cheap, flimsy copies that never work right. This is the original, USA made, Page Clip and it's made of rigid, 18 gauge, nickel-plated, tempered, aircraft steel. Guaranteed not to bend under normal use! It measures 2" x 4" and slips easily in the top of any book, no matter how large or how thick it is. If there is a page to flip, just avoid clipping that page. Works great on text books and cook books too. book accessories, music book stand, music stands for sheet music, music stands for instrument books, book page holder, sheet music holder, page holder, music accessories, piano music books, piano book holder, piano music holder, music stand accessories, piano music stand, music holder, music notes stand, book clip, piano sheet music holder, music book clip, tabletop music stand, piano book clip, table top music stands, grand piano light, music page holder, metal sheet music stand, stand for music book, music clip page holder, music clip, metal music stand, music book clip or page holder, music book holder, sheet music clip, piano page holder, piano lamps for grand piano, piano clip, music holder stand, piano accessories, note music stand, book music, piano music sheet stand, sheet music holder for piano, clips for music stand, desktop music stand, page holder for sheet music, music stand clip, music note holder, music stand page holder, piano music clip page holder, instrument holder, book opener
