This very original infusion bottle is ideal to carry on your various travels. Its separable stainless steel containers can withstand temperatures from -20°C up to 150°C. The hot beverage is fully insulated inside the bottle, allowing you to hold the container without ever being into contact with the heat. This unique patented technology allows you to brew the tea of your choice for as long as it takes in the 0.17 litre top container and then let the tea flow through the stainless steel filter into the rest of the 0.30 litre capacity flask once the bottle has been tilted at a 45° angle. This patented invention ensures that the tea never comes into contact with plastic materials. To know more about its use, please visit our blog.
