My sister & bro-in-law just brought this back from Japan. The funny brush thing is a wooden whisk. The tea is REALLY green and STRONG. Or I didn’t make it right. I can’t read the Japanese directions. It’s supposed to be excellent quality and have a lot of caffeine. I can feel the buzz already so I’m off to see if I can outdo someone’s (whose name is Anne Marie) progress meter, or at least try catch up to it. Sending green tea writing strength to everyone!
