The "Odin & Sleipnir" horn beer mug has a capacity of approximately 650 to 800 ml. For a long lifespan, the mug should only be cleaned by hand with lukewarm water and a soft cloth, as it is not dishwasher safe. Avoid harsh detergents, soaking in water, and hot or highly acidic beverages to prevent damaging the food-safe seal of the natural material.
