Hi, I just bought two four cup packs of your color changing coffee travel cups. I have used them one time and only hand washed like the instructions said. The second time I went to hand wash it I picked up the cup and all of the paint on the outside of the cup came off on my hand. That is so dangerous and completely unacceptable. I had to throw away all of the cups. I took pictures before I threw them away as proof. These cups need to be recalled off shelves and I would like a refund from this company. Thank you, Lindsay.
