Hello. Thank you for viewing. I believe this is a Showa-retro tableware set, likely for guests. The approximate sizes are: Kettle: Width 12.5 cm (to the spout) Height 9.5 cm (to the lid knob) Teacups: Lid: Diameter 7.8 cm, Height 2.0 cm Body: Diameter 7.0 cm, Height 4.5 cm Sencha teacups: Diameter 6.5 cm, Height 6.5 cm I apologize, but both teacups appear to have a grape pattern, but they are not a matching set. You can purchase either one. These items have been stored at home for a long time and do not have a box. I will ship via Mercari delivery.
