This intricately wrought flask carried gunpowder, of which the thumb press on the nozzle would release a measured amount. The flask is most notable, however, for its masterful iron ornament, placing it among the most splendid examples of shooting equipment of its time.

The embossed scenes depict the prophet Isaiah, the coats of arms of Saxony (top) and Denmark (right), crossed swords, and the interlaced initials "AA." These identify the owner of the flask as Prince-Elector Augustus I of Saxony (reigned 1553 to 1586) and his wife, Anna of Denmark, for whom the flask was a New Year's gift, presented as part of a set of hunting implements. The etched decoration on the back shows a rampant lion.
