This Iwatani Home Made Series Cassette Gas Smokeless Yakiniku Grill, "Yaki-Maru," is designed to minimize smoke when grilling yakiniku (grilled meat). I've discarded the cardboard box, but I've used it twice and stored it in the kitchen. I've confirmed that it ignites when a cassette gas is set. There are a few spots of rust on the gas insertion area. Also, the plate is in a clean condition, but there is some remaining dirt on the back of the plate. Please understand that there may be other minor damage and dirt. Since this is a used item, please purchase only if you understand. ^_^
