I'm not trying to collect likes, so please don't like this unless you intend to buy it!!! This is a steaming plate from Terumo in Chinatown. Brand new, unused. The size of the steamer it fits is from 10 cm to 18 cm. (The diameter is 19 cm) By placing the steaming plate between the pot and the steamer, it prevents burning, provides stability, and allows the use of pots up to 19 cm in size. Price is firm. Shipping included.
