A "cone-shaped" shape that deepens the layer of coffee powder is used to extract the flavor firmly. Since it is a large single hole, if you pour it quickly at the speed of pouring, it will be refreshing, and if you pour it slowly, you can change the richness and taste. The wood members are made of natural wood (olive wood), which has a varied and beautiful natural grain, a smooth surface, and is easy to fit in the hand.
