Scandinavian modern vintage Emalox coasters mint in box, forest & apple green enamel metal

Mint in box mid-century vintage Emalox - Norway enameled colored coasters, 3 1/4" in diameter. There's four apple green, four forest green (my color names, I don't know what these colors were called originally).

The boxes show wear, with discoloration to the plastic. The coasters themselves are pristine, I don't believe they've ever been out of the boxes.
