I used this once indoors to drink coffee and have stored it indoors since. This is a kuksa made by a Russian craftsman. The pyrography is very beautiful and delicate, and it has a presence just by being displayed as interior decor. No two patterns are the same, making each one a unique, one-of-a-kind item. Cup size: Approximately 16.0cm wide (including handle) x 7.0cm high Capacity: 300cc Material: Ash
