Size: Outer Vessel: Height 10.5cm, Diameter 9.5cm; Inner Vessel: Height 9.5cm, Diameter 7.5cm. This is an antique sake warmer with hexagonal tin decorations. I believe it is made in China. It is a Chinese sake vessel. Hot water is put in the outer vessel, and Shaoxing wine (laojiu) is put in the inner vessel. Although it is unused, it has become generally discolored due to long-term storage. There may be some scratches and scuffs, but please check the images and purchase accordingly. Thank you for viewing.
