Sendai-doko Octagonal Cup

Since ancient times, the number eight in Chinese characters has been considered auspicious, symbolising continued growth and prosperity, as its shape extends from the present into the future. Octagonal sake cups are designed to fit comfortably and securely in the hand. With their large surface area in contact with the copperware, you can enjoy not only chilled beer, but also cocktails with ice, as the copper enhances the temperature and aroma, providing a full sensory experience.

・Copper is a soft metal. To prevent deformation or damage, do not rub it with sharp objects, bend it or apply excessive force.
・Do not leave drinks or cooked food in copperware for long periods as this can cause verdigris (copper rust) to form. Although verdigris is harmless to the human body, it may affect the taste or appearance of the food.
・Copper has a very high thermal conductivity, making hot objects feel hotter and cold objects feel colder. Be careful not to get burned.
・If oils from fingers or lips or salts remain on the copper and cause oxidation, it may develop a metallic odour or verdigris. After use, wash with a soft sponge and liquid neutral detergent, rinse thoroughly with warm water to rmove oils and dry completely before storing. Scrubbing with baking soda will effectively remove verdigris and oils, neutralising the surface and helping to maintain its shine.
・If you have or suspect you have a metal allergy, please do not use copperware.
・Over time, tinned surfaces can darken and copper surfaces can gradually change colour and texture. This natural aging process has been appreciated since antiquity as the development of a unique "scenery". Please enjoy the characteristic changes of copperware as it matures with age.
