I purchased Luna dishes ( plates, salad plates, bowls and mugs) in 2021. While using them we had one break very easily and ordered a few new ones. Then I was carrying one from the microwave to the table, with my dinner on it, it popped in my hands. They said it's too long to return them. The mugs stain so bad that nothing cleans them. I think the lack of glaze, which makes them charming, is letting water in and then contracting or expanding with heat is the issue.
