This Viking compass tumbler is made from all natural horn with a flat wooden bottom. The inside is coated with a food grade sealant. The outside has been hand polished. This tumbler is great for ale, mead, beer, or maybe your choice of drink is lemonade. Purchase more than one to have a dining set and finish off your medieval dinner in style. Please note there may be a slight odor as this is a natural item. The color and shape may vary and may not be exactly like the picture. This is an all-natural item and you may need to coat inside with beeswax again. In order to do this you will melt the beeswax and pour it in the horn. Wait for it to dry and then pull it out. 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. The variations in their shapes and colors can only be made by nature; thus a horn may have natural blemishes which will not affect its functionality but does verify its authenticity.
