This stunning replica of a real Viking Tankard is made of all natural horn, and is the perfect new piece to add to your collection of cold-brew mugs. Featuring a hand-carving of the fearsome and monstrous wolf Fenrir, who is said to have killed Odin during the events of Ragnarok, you too can feel its gruesome power as you drink from this mug. It is polished to give a lustrous gleam, and a smooth finish, with a food-safe coating on the inside. The base is made of carved wood, so it will sit evenly on flat surfaces. Size and color vary, because every mug is made from all-natural buffalo horn, which gives every one its own uniqueness. *Please wash with a gentle detergent and polish with vegetable oil to keep it from drying out. And from time to time you will want to use beeswax to coat the inside to keep from cracking and the inside drying out. Do not put hot liquids in this item. Please remember this is a natural item and each piece is unique.
