Liebeskind Berlin

Since I might be doing my internship in Berlin, not sure where yet thought, I thought it was about time to acquire something essentially german, or to be more precise - berlinesque.
Now I am the proud owner of a Liebeskind Berlin Abigale purse in an bubble up optic. Although I love everything about this purse, I hate, that I have to take out my Oyster card every single time I enter and leave the tube because the exterior is so thick. Bless German quality ;D
