C830 ARITA DOUBLE WALL MUG 300ML STONE GRAY

A combination of Single-Wall & Double-Wall struction within one Mug

Made in Arita, Japan, it has a single wall near the rim edge and a double wall from the handle to the bottom.
If you double wall the drink to the rim edge, it will be difficult to feel the temperature until you put it in your mouth, which can lead to burns if the drink is hot.
On the other hand, the handle is double-walled, so even when brewing at a high temperature and for a short time using a gold filter, the handle only gets as hot as bath water. This mug has a combination of single-wall and double-wall construction, allowing you to enjoy your drinks comfortably.

Having the narrow rim encourages coffee to flow into the mouth smoothly, allowing the aroma to linger and the flavors to be enjoyed in every part of the mouth.
