Product Details Color: Clear Brand: Avantiz Manufacturer: Avantiz The problem: When you open a book, such as a school notebook, textbook, reference book, recipe book for cooking or making sweets, or a book of music while typing on a computer, the book closes. You have to press the pages repeatedly, or put a weight on the book, but they still shift... Simply placing the book weight on the book keeps the pages open. Your hands are free, and your work efficiency is greatly improved. Thank you for viewing.
