We could fight over the question whether drinking-horns are actually authentical or not. However, fact is, once you visit a medieval or renaissance fair, they're everywhere. Vikings have them hanging from their belts, they stand around in holders on the tables and practically sell themselves at every market stand. They are iconic. They come in different colors and sizes from 0,1 to 1l (or drop us a line how big you'd like one). Should be combined with a leather holder for belts and a forged drinking-horn stand for the table.
All products stem from animals that were ready for slaughter. The horns have been tested by veterinarians, infection with diseases is not possible. So Skøl you vikings, trolls, maidens and champions!
