This is a set of a Japanese-made glass pitcher and a silicone cover. Perfect for tea, black tea, barley tea, or herbal tea. I bought this a few years ago, washed it once, and haven't used it since. Would anyone like it? *There may be some unnoticed oversights. Please refrain from purchasing if you are concerned about minor details, as it has been stored at home.
