This cinch book binding tool is great for making mini albums, recipe books, journals and more. Simply choose the holes to be punched and let the punch bar do the work. Then thread the covers and pages onto the Cinch binding wire (sold separately). The tool secures the binding wire, making it easy. Lastly, the back of the tool will hold the book in place while the punch bar presses the binding wires shut.
