I like this 300g Cafe de Tiamo handle-less milk jug

I enjoy using this milk jug as it puts me in close contact with the temperature of the milk

Obviously it needs to be sold with a silicone rubber sleeve to protect the user from burning themselves, but for my own use i remove the sleeve as i think if it gets too hot to hold you have burnt not only your hand but the milk too

The stainless steel is thin so the heat conducts through the jug without too much delay, and the lack of a handle just makes it easy to grasp
