Collection of Paper Binders

A collection of four paper binders. These all worked by creating a fluted weld along one side of the papers being fastened. Very much on the same idea as a Paper Welder - but much more heavy-duty. From left to right: Fermafix, Turner Multigrip Paper Crimper, Turner "Multigrip" with Adgoods Retarder, Krimp'It. The first three are British made and the last is American.
