Type of dish: Cup Material: Stainless steel This is a set of 6 mugs. All are unused, but two do not have bags. The other four are unopened. The body is stainless steel and has some thickness, which seems to provide good heat retention. The handles are resin, so they should be easy to hold even with hot contents. With their simple design and ease of care, would these be suitable for everyday use or camping? The red handles are quite faded. The two without bags have a little bit of what looks like rust, but it seems like it would be easy to clean off with a little polishing. I received these as a gift and have been storing them, but I would like to pass them on to someone who will use them.
