Like other review and the warning on the packaging Do not put these in dishwasher they fade drastically. The warning should be more clear. DON'T PLACE IN DISHWASHER, as they will fade. The warning is more a recommendation. At the price these should be able to be washed in the dishwasher safely. Considering the amount of fading experienced the quality is not great with these cups, which is a shame as they are a great idea.
