This was given to me when my child was small. My child used it, and it certainly feels hard and durable, with an impression of being scratch-resistant. It had a favorite design, but it wasn't used for very long. There are only a few scratches on a part of the plate, I think. It has been sitting in the cupboard. Plate diameter: Approximately 18cm Deep plate diameter: Approximately 17cm, height: Approximately 4cm I have also included photos. Please take a look. Please understand that these measurements are approximate. Thank you for looking at my item among many others.
