I have opened and used it a few times. This is a brass tea server from "Lue," a brand by Ruka Kikuchi, a brass artist living in Setouchi City, Okayama Prefecture. The tea server is just the right size for one cup of tea. It's also perfect for things like roughly chopped herbs or sauces, in addition to tea. The material is brass, so it has a dull gold color, but the more you use it, the more the shimmering gold color will settle down. We hope you enjoy it, including the changes that occur over time. When you first start using it, you may notice some discoloration, which can be concerning, but it will gradually change to a more subdued color overall with use, so please don't worry too much and use it freely.
