This is a Teranuvo thermal carafe. For reference: As of 2025/10/11, it is sold on Amazon for ¥12,872. It is stylish and functional, and is suitable for keeping hot and cold drinks warm, as well as making cold brew tea by putting ice, tea bags, and water in it. Also, the wide mouth makes it easy to clean the inside with a regular sponge. I learned that Mr. Yu Suzuki uses this, and after purchasing and using it in May of this year, the usability was so great that I bought several for gifts. This item was purchased as a gift and has been stored. It is new, unused, and unopened.
