This is likely a star-shaped cake mold made by KAISER. It's an old item and is no longer sold. I had put it away, intending to use it in the winter. It's a star-shaped baking mold (cake mold). The design is perfect for the Christmas season. I have stored it without using it even once after purchase. It's in a condition close to unused. Diameter is approximately just under 20cm.
