These are Showa retro guinomi (sake cups) and sakazuki (sake cups). There are three guinomi that look like super tiny yunomi (teacups), and one sakazuki with a floral pattern. Information such as the type of pottery, kiln, and whether they are made in Japan or China is scarce, so I don't know. However, they are cute. One of the yunomi-like guinomi clearly has misaligned printing and the colors are not vivid, so I don't think such items would be found on the market today. There are no major scratches, but there are small scratches. Please forgive this as they are old items. Size: Floral sakazuki: Height 2.5 cm Diameter 7.5 cm Guinomi: Height 4 cm Diameter 3.8 cm
