This is a set including the standard set, a yakitori grill net, a tray, and a silicone mat to place underneath. No box or instruction manual included. Used less than 10 times, but there is some slight charring. It might come off if scrubbed, but I haven't scrubbed it. I think there are almost no scratches. Operation has been confirmed. Description: A smokeless roaster with a compact design that allows you to enjoy yakiniku (grilled meat) and vegetables without producing smoke. - Brand: GLAMP - Color: Black - Type: Smokeless Roaster - Included Accessories: Grill net Thank you for looking.
