[About TRAVEL TUMBLER]
Combining stainless steel and glass, LUCE is a carafe with an elegant presence. The lid does not need to be opened and closed each time for pouring. It also keeps dust out and is drip-free. The lid opens automatically when tipped, allowing smooth drip-free pouring. It also helps to keep dust out of the carafe. The mesh filter prevents fine powders from escaping and lets you easily make delicious cold brew coffee and tea. Functional and refined, it can be used in various scenes.​ ​

Your claims about temperature are impossible.
Hot liquid will cool down faster than the cold liquid will warm up, even though both are aiming to reach the same ambient temperature of 20°C.
While perfect insulation is impossible, the initial temperature differential plays a crucial role in the rate of heat transfer. Here's why:
Heat transfer rate is proportional to the temperature difference: The larger the temperature difference between the liquid and its surroundings, the faster the heat will transfer.
Exponential decay: The rate of heat transfer decreases exponentially as the temperature difference gets smaller. This means that in the initial stages, when the temperature difference is significant, the hot liquid will lose heat much faster than the cold liquid gains heat.
Therefore, even though the final target temperature for both liquids is 20°C, the hot liquid will lose its initial 65°C difference much faster than the cold liquid will gain its 16°C difference.
Here's an analogy: Imagine two cars traveling towards each other at different speeds. Even though they both aim to reach the same point, the car starting further away will need to cover a larger distance and will initially close the gap much faster than the other car.
The specific time it takes for each liquid to reach a specific temperature depends on various factors, including:
Cup's insulation quality: Higher quality insulation slows down heat transfer.
Liquid volume: Larger volumes take longer to change temperature compared to smaller volumes.
Starting temperature: The greater the initial difference from the ambient temperature, the longer it takes to reach equilibrium.
However, regardless of these factors, the hot liquid will always cool down faster than the cold liquid will warm up due to the initial temperature differential and the exponential nature of heat transfer.
Do better.
