I heard that the tea bag material for black tea is bad for your health, so I started brewing tea with loose leaves. However, I've accumulated more tea-related goods, so I'm offering this to someone who can use it... I've collected a lot of items, and this one is a beautiful item that I've only used about twice. You put a single serving of tea leaves in the round mesh part and use it. It's convenient, just put it in a mug and pour hot water. You can also use it as a sifter for powdered sugar, matcha, etc. When the tea reaches your desired strength, lift it out. It's made of stainless steel and is hygienic. Size: Approximately 17cm (measured by a layman) I think there's almost no sign of use, but it's used. #stainless
