This is a set of two items sold together: a rectangular baking sheet (tray) for the oven, and a circular tray (for the turntable). These are trays from a previously used oven/microwave. Since I no longer have the oven, the model number and other details are unknown. They have been cleaned thoroughly, but the rectangular tray still has some dirt remaining. The circular tray was hardly used, so I believe it is in good condition. ☆Size (edge to edge) Round: Approximately 30.5cm in diameter, 2.7cm in height Square: Approximately 33 x 33cm, 5.8cm in height - Shape: Round - Shape: Square - Color: Black Thank you for looking.
