Goat Story's 16 oz horn mug is designed to bring a little Viking to your morning cup, with a spill-proof lid and a cross-body carry-strap that converts to a stand to allow you to balance your horn of plenty on your desk between swigs.
I received this as a Christmas present in 2015. It is a metal bottle opener which fits the standard size of beer bottles here in Germany. It was created as merchandise for the exhibition "Wikinger!" in Rosenheim, Bavaria, 2016.
