This 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. The color and shape may vary and may not be exactly like the picture. 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.
