Brown cardboard construction, with a green top label bearing an illustration of the cartridge and marked "50 WINCHESTER 50/.44 FLAT RIMFIRE CARTRIDGES/RIFLE CARTRIDGES" above the New Haven address, and a pair of orange end labels with a red "W" behind "44 FLAT/Rim Fire/Cartridges." The underside of the box is stamped "58/MADE IN U.S.A." The box contains 49 rounds.

The box is fine showing edge separation on the short ends of the body of the box and a tear on a long side of the lid with some typical edge ware. Much of the end orange end labels remain and most of the green label remains with overall clear printing.
