I found this in the cupboard while cleaning out my parents' house. It seemed cute, so I brought it home, but I didn't know how to use it. I looked it up and it seems like it's for tea, herbal tea, or even regular tea. It's made of heat-resistant glass. It had been sitting for a long time and was dull, but after washing it, it turned out to be glass and became clean. However, the handle and lid? are made of a plastic-like material and have fine scratches. In the third photo, the round hole, I looked it up and it seems like there should be a plastic lid, but it's missing. In the ninth photo, for reference of the height... next to it is a 2-liter plastic bottle. This is an old item, so please understand that it has aged and been stored at home for a long time. Please only purchase if you understand that it is a used item.
