Long Dan, dragon's egg, is a classic design with long history, whose earliest record can be found in literature of Qing dynasty, and the oldest surviving piece even earlier, from Ming dynasty.
 
This lovely Long Dan has a very simple shape with smooth curve, wonderful in workmanship and feels very nice in the hand. It is a practical teapot, with spacious inner space, and has a small capacity perfect for tea sessions among 1-3 persons.
