This is Naozumi Tanaka's chahai! Naozumi-san is also well-versed in Chinese tea and makes many chahai and teacups. They're very cool! You can use it for Japanese sake, to cool down hot water, for sauces, or of course, as a chahai. You can even display a single flower in it. It's versatile. It's new and unused, but has been stored in a cupboard for a long time, so I've listed it as "like new." If you can accept this, please consider it! Approximately 9.5cm tall, 14cm wide, and 9cm high.
