San Francisco is very cold and I always want to have hot drink nowadays.
Nyankichi : then, you will love this! (He shows MUJI's tumbler)
The Muji's tumbler will keep the drink's tempartuer, so your tea will be still hot after one hour you make.
Frog : Maybe tumbler is better than coffee cup during winter.
I personalry like this Muji's tumbler, but other tumblers are also good for winter season!
