Wholesale thermal vacuum airpot flask
It is a vacuum-insulated airpot flask with a pressing pumping button on top. It is designed with a child safe lock on top as well.
Every airpot will be passed through a 550°C vacuum for more than 30 minutes to make the double wall a vacuum condition, which makes the airpot able to keep hot for 24 hours and cool for 12 hours. As well, its useful life is longer.
