It's a titanium double wall mug.
It has a dual structure, so it is a perfect mug for cold drinks because ice does not melt and condensation does not occur well compared to the single wall, which has a single layer structure.
It also has high warmth, so you can drink warm until the end when you drink a warm drink.
You can rest assured that the edges do not get hot even with hot drinks.
