Query: NOT dishwasher safe!

I chose these mugs specifically because they were advertised as being dishwasher safe. When the package arrived, the instructions inside the box stated that baking the mugs makes them "hand-washable," but you better wash it quickly since they also state "Do not soak your mug." The directions go on to state "Do not place your mug in the dishwasher or microwave as doing so may remove paint over time," which is a complete contradiction of what was advertised online.The images of the product are also misleading, since each mug shown online has painting near the rim, and the instructions state "Do not paint 1/2" from rim of mug."These were a big disappointment and I will be sending them back.
