Keep the temperature of the drink delicious! I tried using the "heat retention mug" developed by Thermos.
A mug with a vacuum insulation structure that has excellent heat retention performance. A stainless steel body, holder, and lid are included in the set. The thin lid is very simple. It is not airtight, but it is useful as a dust shield.
When I tried making hot coffee, the temperature changed from about 75 degrees to about 65 degrees after 30 minutes, about 57 degrees after 1 hour, and about 52 degrees after an hour and a half. Depending on the environment in which it is used, the temperature changes slowly, so you can enjoy the taste of the drink for a long time. Of course, it is also effective for keeping cold drinks cold. Unlike ordinary mugs, the outside of the container does not get hot and does not condense. Since the mouthpiece is rather thin, people who are accustomed to thick cups may feel a little uncomfortable at first.
The size introduced this time is "240 ml", and the manufacturer's suggested retail price (excluding tax) is 2,800 yen. There is also a larger 350ml (11.83us fl oz) model. There are various colors such as white, light pink, and espresso, so why not choose one and make use of it?
