Good evening. The numbers and name on all 6 our Tommee Tippee bottles had faded. We love the bottles and our son loves the bottles but it is rediculous. Tommee Tippee is expensive and then the bottles fade and make the water look yellow. We only wash the bottles with sunlight liquid. We would appreciate it if you could look into this and resolve this problem. We would really appreciate it if this could not happen. As we really want to use Tommee Tippee with our future kids as well. But it is not worth buying if the bottels look liks this after a few months. For that amount of money it should be a lot better quality.
