Chicago Screw Posts are a removable and quick way to secure loose sheets of paper together with a clean, finished appearance. With no special equipment or binding machine necessary, you can quickly bind samples, swatch books, pictures, and more. These 1/4" aluminum screw posts come in two halves, and as the name suggests, one is a screw, and the other is the post. Once your materials are punched, slip them onto the long post side, and close the bind by rotating the screw end together. With a smooth exterior finish, you can change the contents without having to worry about scuffing. Specifications: - Color: Black
