Bin only just pretty sad. Have the thermos always washed by hand but as seen in the pictures is crumbling now unfortunately paint from. This is quite annoying the "dark cocoa" or German Schockobraun wikrlich was a very nice color .... :-(
I can not remember, that's like thermos.
I wash this mug vice allways with hand. But like you see in the pictures, is less the color step by step.
