These mugs are smaller than I expected. Also, I had some doubt as to whether they were actually safe for the microwave. It doesn’t state Microwave Safe on the bottom of the glass. The language is not English. I know that the description on Wayfair’s website states that they are safe for the microwave, and I had to go back and verify by doing the water test on one. The painting of the bird and flowers looked more appealing in the picture on the site. Overall, they are ok, but not quite what I was hoping for.. Maryg. Decatur, GA. Tue Jul 29 2025
