Nice for outdoor use. Not porcelain. Plastic. Didn't realize when purchased.

I just got these in the mail and they are plastic! I guess I did not know what "Tritan" was. For what I paid for them I was expecting them to be a sturdy ceramic or like type material. These look and feel cheap, not what I thought I would be getting. I am initiating a return.

I was a little disappointed with the quality of the mugs. They are very lightweight. I kept them anyway for use at our cabin.
