Put your EZMount or clear stamps on the panels and then write on the tab what you stored on that panel. The panels also have a universal punched hole so they fit into both European style and standard letter sized 3-ring binders. This package contains five white panels 11-3/4 x 8-1/2 inch. Made in USA. Panels fit into the EZ Mount Enclosed Binders (Item #SS21) for dust-free storage and easy retrieval.
