9 inch square plate is handmade and hand painted in the Manufaktura factory in Boleslawiec, Poland. Microwave and dishwasher safe. Oven safe up to 450 degrees. I have a variety of mix and match I am selling. They are beautiful - in good condition but I have moved and am selling half of my collection. See additional postings for other patterns. This plate has an indentation in the back (see photo) it came that way - it’s smooth but I wanted to note.
