Material: Pottery/Porcelain This is an interior plate made of pottery. Brand new, unused. It's cute with a starfish attached. It's cute as an accessory holder or just displayed as is. It seems it cannot be used as tableware. It's 11.5 cm wide and 9 cm long. It would also be cute as a gift. It will be wrapped in bubble wrap for shipping. I have several, so please comment if you'd like to buy more than one. I also have other marine goods.
