500ml/17oz 304 Stainless Steel Water Bottle Double Layers Coffee Mug Milk Cup With Plastic Lid And Handle

Very nice and convenient! It doesn't keep heat for very long, but it's enough to comfortably drink hot drinks at home or at work. I bought it for the second time, in a different color.

As soon as it arrived, I wiped it with edible oil inside... but polishing agent came out.
I washed it and drank beer with it... but I don't think the coolness will last long... there's dew forming on the outside...ㅠ
The cup is thin and the part where the stainless steel and plastic touch doesn't seem to fit... The plastic sticks out more and isn't smooth.

It is a stainless cup with a plastic case with a handle.



There is no warming or cooling function.



The lid seems well made. Even if you pour water in it and turn it over, the water doesn't leak.



It's very good.

The mug is excellent. With the lid, it keeps the temperature and doesn't leak. The only warning is that when boiling water, you need to close the lid with the valve open, otherwise the lid will be pushed out by the steam pressure, and then close the valve.

Nice cups, great for camping. I still need to get used to the fact that if something is advertised as 500ml it means 500ml filled to the brim, not 500ml and you can still carry it around without spilling. But holds 450ml comfortably
