I purchased this a few years ago but am selling it because I haven't had a chance to use it. There are no noticeable scratches or stains. *There is a small scratch on the bottom, but it shouldn't affect use.

It's a great system design that allows you to store a Gigapower Gas 110 or Gigapower Stove "Ground" inside when packed away, and it can also be stacked with other deep-type cookers. Material Aluminum This metal is lightweight, has excellent thermal conductivity and is non-magnetic, and also has good surface treatment properties such as anodizing.
