This is a grill plate from GRILLER. I purchased it about 4-5 years ago and have used it about 10 times. It has been stored at home. There are some scorch marks, stains that won't come off even after washing, yellowing, and scratches, but it's still usable. - Type: Grill plate - Material: Cast iron - Features: Protrusions on the bottom - Brand: GRILLER Thank you for looking.
