By simply touching the LED screen, you can instantly view the temperature of your liquid without the need to test it with your mouth and risk getting burned. Our products are designed to be durable and can maintain the temperature of your beverage for up to 6 hours at a temperature above 42 °C, and up to 5 hours when cooled below 10 °C, thanks to the vacuum insulation in our cups and bottles. This is longer than other vacuum bottles available in the market. You can rest assured that our products are made of safe and healthy materials, with the inner wall crafted from food-grade 316 stainless steel and the outer casing constructed using high-quality 204 stainless steel. Additionally, our waterproof LED display is designed to be completely submerged in water, making it easy to clean and maintain.
