This large spouted form could be used to pour any number of liquids. I'm fond of how his Ryokuryu glaze contrasting against the white inner glaze, and the glaze sliding down the inner walls gives this a very organic feel.
If you tried to fill this up, I think you'd be able to put about 750 ml of liquid in it, so consider using it for hot beverages, presenting cold sake at the table, or maybe even for thin sauces. Only one available.
