These are Spanish-made cazuelas (baking dishes) from Baker. They can be used on direct heat, in the oven, microwave, and dishwasher. This is a set of 7, including 5 small cazuelas with a diameter of 12cm and 2 large cazuelas with a diameter of 20cm. Although unused, some of the packaging shows signs of dirt (see photo 3). One of the 20cm cazuelas has a small chip on the bottom (see photo 7). - Sizes: Approximately 12 cm outer diameter x 3 cm height Approximately 20 cm outer diameter x 4.8 cm height I am clearing out my parents' house. The purchase date is unknown. For those who don't mind, are familiar with, or can use these. I may not know the details if you ask. Please understand. Please refrain from price negotiations as I am busy with the cleanup.
