Material: SUS304 all steel
① cup
All steel 500ml: height 24.5cm, diameter 7.2cm
All steel 750ml: height 27.5cm, diameter 8cm
1000ml all-steel: height 29.5cm, diameter 8.5cm
All steel: 1500ml: height 34cm, diameter 9cm
② heat preservation aging
Measured heat preservation aging is more than 30 hours; at room temperature of about 23 ° C, it is filled with hot water that has just boiled at 100 ° C, about 85 ° C for 6 hours, and about 55 ° C after 20 hours. Note: Obtained by using 1000ml test.
The heat preservation aging is directly proportional to the initial water temperature and the amount of water filled. Installing warm water, or half a cup of water, will reduce the heat preservation aging.
