This is a plate set purchased at Francfranc. It is a set of 4: 1 medium plate, 1 small plate, and 2 slightly deep side plates. We prefer to sell them as a set to account for shipping costs. If you wish to purchase them individually, the price will be higher. The sizes are approximately 20cm for the medium plate, 15.5cm for the small plate, and 14.5cm in diameter and 4cm in height for the deep side plates. I purchased these along with a pink series, but I rarely use the blue ones, so I would like to pass them on to someone who will use them. This is a used, beautiful item with low usage frequency.
