These magnetic sheets take a firm hold on your metal dies.  Package contains 3 magnetic sheets for safe storage and viewing of dies.  Each sheet measures 7.0625 x 8.9375 x .0625 inches; they seem to hold quite a few dies, too!  They are designed to fit inside the Magnetic Die Storage Case (Item # 6978AB, sold seperately), but can certainly be added to a similar size carry case.
