This is a grill pan set for a HITACHI built-in gas range. I purchased the range a year and a half ago, but I replaced it because the glass top broke. The grill pans are relatively clean and have been used very little (the flat pan has never been used). Individual sales are also possible, so please comment if you have any questions. The model I was using was HT-M200HTF, but I think it can also be used with the same series (please confirm this yourself).
