These are original German army earmuffs. Very cool piece of German winter equipment. They fold almost completely flat to fit in a pocket or wherever. They are black on one side and a pink/faded red on the other side. They are in decent, wearable condition but does show some wear.
These are pictured in two 1930s catalogs. The earlier catalog from 1931 has the price is Pfennings (Pf) while the other from the late 1930s has the price is Reichsmarks (RM).
