Irridescent mermaid Starbucks 12 oz mug ceramic

Irridescent mermaid Starbucks 12 oz mug ceramic coffee cup, has a irridescent sheen over the cup that picks up yellow. Green, pink. Purple. Lots of shine. I bought this for myself. Forgot and put in microwave ( please do not microwave!) and when I took it out the metallic paint had heated up and came off where my fingers had been gripping. Her hair below chin and part of sea fern is missing paint. Please zoom in. So…. This gorgeous coffee mug is flawed. And price reflects the wear. No lid. I usually throw away because they don’t stay on that well. Probably used and washed 3 times.
