Vintage Hroar Prydz Norway Enamel Crystal Salt & Pepper Shakers in Original Box For Sale

This little set of enamel top salt and pepper shakers come in their original presentation box. There is no wear or pitting on the inside of the shaker caps which tells me they were not used. The sterling portion of the lid (is dark and needs polishing) is marked but I can\'t make out what it says. The box has a dark ring on the lid and another dark spot.
