Eco Chic Thermal Coffee Cup Ditsy

Love the cup but it washes off

This is my 2nd cup in this pattern. My first just looked a bit battered so I thought I'd replace it. The new one I've had since December and the pattern is flaking off. It's only ever been hand washed in eco washing up liquid. Incredibly disappointed as it's such a lovely travel mug. Think I will get a plain one in future
