NOT DISHWASHER SAFE!,
This review is from: Paladone Tetris Heat Change Mug (Kitchen & Home)
My mistake obviously as the manufacturer states that this is not for use in a dishwasher, but inevitably if you have a dishwasher there is a risk this will get loaded in with the rest. This happened to me after a few months and I quickly found that the white lines and some of the other graphics are in fact transfers and will slide around getting stuck to other items if you're not lucky. The colour-change function still works but one accidental encounter with a dishwasher will ruin the item.
