This is an aluminum hot sandwich maker of unknown manufacturer. The size of the plate that holds the bread is about the size of a Lunch Pack. It seems that you would need to cut off the crusts of commercially available bread. I bought this, but I haven't used it because I felt it was a waste. There is no box or instruction manual. Of course, the Lunch Pack in the photo is not included! Only the main body is. I've seen videos of people heating up Lunch Packs with it, so that seems like a good way to use it. Bread size: 11.5cm x 10.5cm x 2.6cm Length: 27.0cm
