Best Travel Mug I ever used. Keeps the temperature perfect to my liking the whole day - exactly the temperature I make in the morning. Good size for enjoying your tea through the day . Loved it so much, that ordered other sizes for different drinks I use through the day- like 360ml for moring coffee and 480 for water , all in different colours. Got one as a gift to my best friend and she loves it for being safe and not leaking ever in a bag as well as the temperature keeping and she ordered other sizes as well. Definitely Will buy those mugs again for presents .
