Wow! These genuine old boxes of American mica flake sparkles date to the 1930's! Manufactured by "Mica Mountain Mines, Salt Lake City, Utah," each box of mica flakes is still in original, never-opened condition. These large-size, satiny flakes are perfect for old-style Christmas decorations, and match perfectly the mica flake sparkles which were used to accent Santa and Belsnickel figures in Victorian times. Each box is 7" high and 4¾" wide by 1½" deep and contains about 5½ ounces of American-mined mica.
