These are ALL 3D heavy cast iron, not just thin stamped tin. These were used on higher quality trunks to protect the edges and to enhance the look of the trunk. Can be attached with trunk nails. 4 matching fancy scrolled side edge corner braces/protectors.
This product would be ideal for antique enthusiasts, historians, or decorative collectors who want to secure and add a finishing touch to their vintage cast iron steamer trunks.
