Steel box

Abstract

The invention refers to a box (steel box) constructed to contain multiple steel dies (30) and includes a lid (10). The lid (10) includes an extension (22) extending from the body and at least one shaped hole (23) passing through the extension (22) longitudinally* so that one of the multiple steel dies (30) is selectively removed from the body (10), and one steel die (30) is attached to at least one shaped hole (23) of the lid (20). Then, the lid (20) is moved to verify the stamping position of a steel die (30) so that a steel die is struck to stamp at least one document or symbol.
