HITACHI Oven Range MRO-F5Y Black Plate Oven/Grill Plate Size (approx. cm) Maximum Outer Diameter Width 29.6, Length 28, Height 2.3 Please note that there may be some errors due to amateur measurements. I have not used this for oven cooking, so it has been stored unused in its original bag (the bag it came in when purchased). No smokers, no pets. Instruction manual included (with folds). It may be lightly folded for shipping. Since the black plate is the main item for sale, and the black plate is unused, the product condition is listed as new and unused. No smokers, no pets. Box
