The tumbler made of tin, known as a stable metal that does not rust easily, conducts heat very well and can be served moderately cold.
The tumbler is a traditional craft designated by the Minister of Economy, Trade and Industry in 1983, and is produced by traditional craftsmen certified by the Japanese government, and has been adopted as a souvenir for the G20 Osaka Summit 2019. Due to the custom-made nature of this product, it takes about 30 days for delivery.
