This is a ceramic handmade sake cup and bottle set that contains one vessel and two cups. The radium ore used in the glaze of the bottle generates ions inside the bottle, which makes the drink you put in it taste mellow after about a day. You can store sake, wine, or other alcoholic beverages in the bottle, as well as water. Since the coloring of the product is determined by the balance of the flowing colors of the glaze, each piece has a different texture. The modern silhouette of straight and curved lines is beautiful, and the elegant colors and textures will make your table look gorgeous. The design can fit in a refrigerator pocket and is easy to hold with one hand. This sake set is an amazing gift for those who love Japanese sake.
