My requirements were that no dirt in the cups, the lid with minor knocks the spilling of drink prevented and the cup the drink not 5-6 hours scalding hot holds. 1. On the cover edge (outside) are 2 offset rubber fins attached the lid well located, retains the heat and a good seal with lighter shock (there are sporadic Drops of the drink herraus but that's ok for me and something else I never wanted to). 2. I have it now is not stopped but after about 30 minutes at Becher closed the drink for me aufjedenfall still well hot. ----- ----- the height of the cup without a lid is 9cm. With lid 11.7 cm.
