Made of titanium (not aluminum). - Type: Cookware set - Material: Titanium - Size: Compact - Storage: Comes with a mesh storage bag - Features: Stackable Used three times. The larger frying pan shows some soot, but it should not affect use. Close-up photos have been added in the 5th and 6th images. (It may look uneven, but it's just a color change) I am offering it at a reduced price due to this. Please contact me if you have any questions.
