Original War Time German military issue. These are original WH issue lenses normally stored in the small box on the inside of the lid.  Packed in cellophane wrappers like the originals.  They are excellent replacements for damaged or missing lenses on Wehrmacht issue Gas Masks or canisters since they are made exactly the same.  One pair of clear lenses.  Issued but in unused serviceable condition.  Labels, manufacturers and dates may vary,
