These cups are ideal for drinking sake or tea as in many countries in the East. The vessels also work well for tea lights or to hold little treasures.
The cups are part of the Umbra Collection, where a refined clay slip used centuries ago containing minerals & oxides is applied by hand during the most fragile stage, referred to as bone dry. The outcome is one unique coloration each time, and varieties in color, texture, and application will give the cups their distinctive appearance.
The vessels you receive will vary from the pictures as they are individually made. The asymmetry, texture, and irregularities of the cups are expressions of the artisan that created it.
