This is a mini tea set collectible in blue and white floral pattern. No makers mark or other definitive markings so not sure if Chinese or Japanese. It's a mini tea pot with removable lid, with 4 mini cups on a tray. Tray is 5 1/2 inches long. Teapot is 3 inches tall with lid, and from spout to edge of handle is 4 1/2 inches. Cups are about 1 3/4 inches high. They feel like they are made of ceramic. Lovely blue and white floral pattern. Great for the collector. Used, no box, but in excellent condition, no chips, or cracks.
