Corner Pipe Gusset Plates (Set of 25)??

This is a double-sided plate for square pipes used in construction and building formwork. It was used only once, but is no longer needed, so I am selling it.
There are 25 pieces in total.
I believe they are in good condition visually.
However, there may be some overlooked details, so please judge from the photos.
If anyone is interested, I would appreciate it.
