I've got this cup for my housewarming party about 3 years ago. I saw it on the airport in Leica shop and I liked it so much. I was going back home from duty free with my colleague and later on it revealed that he somehow managed to go back to this shop before our flight and get one for me.
I don't use it often, it is very special one. Always brings warm feelings and reminds me of this very first emotions after having my own place on Earth :)
